The cost of a single ticket depends on the number of tickets, t, purchased in a group, as represented by the function C(t).
C(t) = $18.50 1 <_t < 12
$16.00 12<_t < 20
$14.50 20<_t
What is the total cost for 20 tickets?
A.)$14.50
B.)$16.00
C.)$290.00
D.)$320.00
Answer:
C. $290
Step-by-step explanation:
We see that,
The cost of the single ticket is given by,
[tex]C(t) =\left\{\begin{matrix} 18.50, &1\leq t\leq 12 \\ 16.00, & 12\leq t\leq 20\\ 14.50, & 20\leq t\end{matrix}\right.[/tex],
where t = number of tickets.
As, we have,
When t = 20, the value of C(t) is $14.50.
That is, the cost of 20 tickets = 20 × 14.50 = $290.
Thus, the total cost of 20 tickets is $290.
If f(x) is a linear function, what is the value of n?
Answer:
Option C. 13
Step-by-step explanation:
Since f(x) is a linear function then we can rewrite the function in the form of an equation y = mx + c
where m is the slope of a line.
Since line passes through two points (3, 7), (9, 16)
Therefore m = (16 - 7)/(9 - 3) = 9/6 = 3/2
Now we know a point (16, 26.5) also lie on the line so by putting the values of m, x, and y in the equation.
y = 3x/2 + c
26.5 = 3×16/2 + c
c = 26.5 - 24 = 2.5
So the equation is y = 3x/2 + 5/2
y = 1/2(3x + 5)
If a point (7, n) lies on the line then
n = 1/2(3×7 + 5) = 1/2(21 + 5) = 26/2 = 13
Therefore n = 13 is the answer.
What is an equation of a line that is perpendiculauation is 2y=3x-10 and passes through -6,1?

Jessica paid $13.24 for a 3.41-pound bag of shrimp at one store. The following week, she paid $18.99 for a 4.96-pound bag at another store. Find the unit price for each bag. Then state which bag is the better buy based on the unit price. Round your answers to the nearest cent.
Answer: 1st answer is 3.88 lastly the 2nd is 3.83
Step-by-step explanation:
The bag with price $18.99 for a 4.96-pound bag is best to buy.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
for example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jessica paid $13.24 for a 3.41-pound bag of shrimp at one store.
So, Jessica paid for one pound of shrimp = 13.24/ 3.41
= $3.88
= $3.9
and, he paid $18.99 for a 4.96-pound bag at another store.
So, she paid for one pound = 18.99/4.96
= $3.8286
= $3.8
Hence, the bag with price $18.99 for a 4.96-pound bag is best to buy.

Andy is buying carpet squares for his living room. the length of the room is 20 feet, and the width is 16 feet. each carpet square covers 4 square feet. how many carpet squares will andy need to purchase to cover the room
Answer:
andy needs 80 carpet squares
Step-by-step explanation:
Final answer:
To cover the living room, multiply the room's length by its width to get the area in square feet (320 square feet), then divide by the area that one carpet square can cover (4 square feet), resulting in 80 carpet squares needed.
Explanation:
To calculate the number of carpet squares needed to cover Andy's living room, we start by finding the area of the room. The area is the product of the length and the width, so we multiply the room's dimensions: 20 feet (length) by 16 feet (width). This calculation gives us an area of 320 square feet. Next, we divide the total area by the area that each carpet square can cover. Since each square covers 4 square feet, we divide 320 square feet by 4 square feet per square to determine the number of squares needed:
320 square feet ÷ 4 square feet/square = 80 squares.
Therefore, Andy will need to purchase 80 carpet squares to cover the living room.

Which pair of measurements is not equivalent?
450 mm, 4.5 m
250 cm, 2.5 m
4 km, 4,000 m
1.2 cm, 12 mm
Final answer:
The pair of measurements that is not equivalent is 450 mm and 4.5 m.
Explanation:
When comparing pairs of measurements, it's important to convert them to the same unit before making a comparison. Let's examine the pairs to determine which one is not equivalent:
450 mm is convertible to meters by dividing by 1000, as there are 1000 millimeters in a meter, giving us 0.45 m. This is not equal to 4.5 m.250 cm is convertible to meters by dividing by 100, since there are 100 centimeters in a meter, resulting in 2.5 m. Hence, 250 cm and 2.5 m are equivalent.4 km converts to meters by multiplying by 1000, as there are 1000 meters in a kilometer, resulting in 4000 m. Therefore, 4 km and 4000 m are equivalent.1.2 cm is convertible to millimeters by multiplying by 10, as there are 10 millimeters in a centimeter, giving us 12 mm. So, 1.2 cm and 12 mm are equivalent.The non-equivalent pair is 450 mm and 4.5 m. All other pairs are equivalent after conversion.
