Jim makes and sells denim knapsacks for $10.50 apiece. The knapsacks cost $7 apiece to produce.
Jim makes ____% profit on each knapsacks.
Show your work.
A. 33
B. 50
C. 75
D. 125
In this problem, to solve for the gross profit, you have to deduct the cost of each knapsack to its selling price.
The gross profit of Jim is $3.50 ($10.50 - $7).
To compute the gross profit rate, you have to divide the gross profit ($3.50) to the cost of each knapsack ($7).
$3.50 / $7 = 0.5 or 50%
Therefore, Jim makes 50% profit on each knapsack.

Using real life quantities,how will you justify that the derivative of constant is 0?
The derivative of a constant is zero can be understood by comparing it to traveling at a constant speed, where there is no change or acceleration, hence a rate of change of 0. This is analogous to the slope of a horizontal line (representing a constant function) on a graph, which is also 0.
Explanation:Using real-life quantities, one can justify that the derivative of a constant is 0 by considering the concept of speed. Imagine you are traveling in a car at a constant speed of 60 km/h. The speed does not change over time, meaning there is no rate of change or acceleration. In terms of calculus, this constant speed (constant function) has a rate of change of 0, which is its derivative.
The derivative, in a broader sense, measures the rate of change of a quantity. A constant value does not change, and hence its rate of change, or derivative, is 0. This concept can be geometrically represented as the slope of a line on a graph. A constant function graphs to a horizontal line where the slope, or rise over run, equals 0. Thus, similar to the constant speed with no change, the derivative of any constant value is always zero.

1 you have 75% of your pay direct/-deposit how much is given to you as a check per week ?
2. of the amount direct-deposited problem 1 you have 50% placed into a savings account how much is deposited in the savings account each month?,
Final answer:
The student takes home a check of $25.94 each week after deductions and direct deposit. Of the amount direct-deposited, $38.92 is placed into a savings account weekly, resulting in $155.68 being deposited into the savings account monthly.
Explanation:
To solve the first problem, we must start by calculating the gross income for one week of work:
Gross income = Hourly rate × Hours worked per week = 13.76 × 10 = $137.60Next, we calculate each of the deductions from the gross income:
FICA = Gross income × FICA rate = $137.60 × 7.65% = $10.52Federal tax withholding = Gross income × Federal tax rate = $137.60 × 9.8% = $13.48State tax withholding = Gross income × State tax rate = $137.60 × 7.13% = $9.82Now we calculate the total deductions:
Total deductions = FICA + Federal tax + State tax = $10.52 + $13.48 + $9.82 = $33.82The net income after deductions is:
Net income = Gross income - Total deductions = $137.60 - $33.82 = $103.78We then determine the amount directly deposited:
Direct deposit amount = Net income × Direct deposit percentage = $103.78 × 75% = $77.84The remaining paycheck given as a check each week is:
Check amount = Net income - Direct deposit amount = $103.78 - $77.84 = $25.94For the second question, we already know from the scenario that $77.84 is directly deposited. We just need to calculate the amount that goes into the savings account:
Savings deposit per week = Direct deposit amount × Savings account percentage = $77.84 × 50% = $38.92 per weekTo find the monthly savings deposit, we assume there are 4 weeks in a month:
Savings deposit per month = Savings deposit per week × 4 = $38.92 × 4 = $155.68 per monthwhat are the similarities between reflections translations rotations and dilations?

Scott and Harry went cycling every day. They increased the number of minutes of cycling every week as described below: Scott: Cycled for 10 minutes every day in the first week, 15 minutes in the second week, 20 minutes in the third week, and 25 minutes in the fourth week. Harry: Cycled for 10 minutes every day in the first week, 20 minutes in the second week, 40 minutes in the third week, and 80 minutes in the fourth week. Which statement best describes the methods used by Scott and Harry to increase the time they spent cycling? Scott's method is linear because the number of minutes increased by an equal number every week. Harry's method is linear because the number of minutes increased by an equal factor every week. Both Harry's and Scott's method is exponential because the number of minutes increased by an equal factor every week. Both Harry's and Scott's method is exponential because the number of minutes increased by an equal number every week.
Answer:
Scott's method is linear because the number of minutes increased by an equal number each week.
Arithmetic progressions use the linear method.
The graph proves it, by obtaining a straight line.
Step-by-step explanation:
Scott used an arithmetic progression, with a ratio of 5, that is adding 5 to the value of each previous week.
Let us call the time in minutes of each week, so the arithmetic progression is of the following linear form:
S1 = k0 = 10
S2 = k1 + 5 = 10 + 5 = 15
S3 = k2 + 5 = 15 + 5 = 20
S4 = k3 + 5 = 20 + 5 = 25
See attached chart.
Harry used a geometric progression, with a ratio of 2, that is multiplying by 2 the value of each week.
Let us call time in minutes of each week, so the geometric progression is of the following exponential form:
S1 = k0 = 10
S2 = k1 x 2 = 10 x 2 = 20
S3 = k2 x 2 = 20 x 2 = 40
S4 = k3 x 2 = 40 x 2 = 80
See attached chart.
Let's analyze the four options given:
Scott's method is linear because the number of minutes increased by an equal number each week.
True: The graph proves it, by obtaining a straight line.
Also, Arithmetic progressions use the linear method.
Harry's method is linear because the number of minutes increased by an equal factor each week.
False: The graph shows that it is not linear, a straight line is not obtained.
Both Harry and Scott's method are exponential because the number of minutes increases by an equal factor each week.
False: Scott's method is linear.
Both Harry and Scott's method are exponential because the number of minutes increases by an equal number each week.
False: Scott's method is linear.

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Charge for week = $170
earnings from leaves raking = 58.35
Earnings from snow shoving = 85.80
Total earnings = 85.80 + 58.35 = $144.15
So, he need more
=170 - 144.15
=$25.85
Hence, He need $25.85 more to pay.

What type of graph is useful when depicting piece rates?
A. Bar graph
B. Scatterplot
C. Slope
D. Linear graph
A linear graph is most useful when depicting piece rates as it clearly shows the continuous relationship and trend between the number of items produced and the pay received, represented by a positive, negative, or zero slope.
When depicting piece rates, which relate the payment an individual receives to the number of pieces produced or tasks completed, a linear graph or line graph is often most useful. Linear graphs effectively illustrate relationships between two variables, such as the number of items produced (on the x-axis) and the amount of money earned (on the y-axis), highlighting trends and changes over a range of values. A bar graph may be best to illustrate comparisons when showing the relationship of separate and distinct categories. However, in the context of piece rates, where there is a continuous relationship between work done and pay received, the connected data points in a line graph provide a clear visual of the rate of payment as it changes with the number of pieces.
Understanding the appearance of slopes is essential in reading graphs. A positive slope indicates an increase or upward trend in the relationship between the two variables, a negative slope represents a decrease or downward trend, and a zero slope indicates a consistent, flat relationship with no change over time.
