Marketing Chapter 3 Test Questions
1. A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater estimates that average nightly ticket sales will be $1,750. What is the percentage change in the average number of customers the theater has each night? (Express your answer in whole numbers; round decimals up or down).
Answer is 0.17
2. A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater estimates that average nightly ticket sales will be $1,750. What is the percentage change in ticket prices?
Answer is 0.40
3. A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater estimates that average nightly ticket sales will be $1,750. What is the elasticity of demand in this situation? (Hint: Elasticity of demand is determined by calculating the ratio of the percentage change in the quantity demanded over the percentage change in price.)
Answer is 0.425
4. Study the following data for a product:
Price Amount produced Amount demanded
$200 100,000 7,000
$100 80,000 35,000
$75 45,000 45,000
$50 30,000 70,000
$20 15,000 90,000
Find the market price. ________? Answer is $75
Step-by-step explanation:
1.) The average nightly ticket sales can be calculated as
Average sales = Average no. of customers per night x Charge per ticket
For the second night, we have
$1750 = (N)($7)
This gives us N = 250.
So, the average number of customers decreased as a result of the price increase.
To calculate the percentage change, we use the following formula:
% change = [tex]\frac{250 -300}{300} X 100[/tex]
We have -17% change in the average number of customers the theater has each night. The negative sign indicates a decrease in the number, which is consistent with our calculations.
2.) % change in prices = [tex]\frac{Final price - Initial price}{Initial price} X100[/tex]
Therefore, we have 40% change in the cost of ticket per person, which reflects an increase in the prices.
3.) Elasticity of Demand = [tex]\frac{ percentage change in quantity demanded}{percentage change in price}[/tex]
Hence, we have [tex]\frac{-17}{40}[/tex] = -0.425
This stands consistent with the Law of Demand - as the price increases, the quantity demanded decreases.
4.) Market price is obtained by looking for a point where the quantity supplied equals the quantity demanded. From the table we see that at $75 price, there is a demand for 45,000 units of that product in that market, which the suppliers are willing to supply. Hence, that defines the market price for that product.
In a study of 300 pregnant women with good to excellent health diets, 95% had babies in good or excellent health. How many women in this group had babies in good or excellent health?
For this question, just multiply the number (300) by the percent (.95)
Your answer is 285 women
To determine the number of women with babies in good or excellent health, we multiply the total number of women (300) by the percentage of women with healthy babies (95%). We find that 285 out of the 300 women had babies in good or excellent health.
Explanation:In the study mentioned, it is stated that 95% of pregnant women with good to excellent health diets had babies in good or excellent health. The total number of women considered in this study is 300. To calculate the exact number of women who had babies in good or excellent health, we can apply the concept of percentage which means 'per 100'. So, 95% of 300 women equals (95/100)*300 = 285 women. Therefore, out of 300 women, 285 women had babies in good or excellent health.

Solve for xxx.
−9x+2>18 OR 13x+15≤−4
Answer:
x < -19/13
Step-by-step explanation:
The solution to the inequalities −9x+2>18 and 13x+15≤−4 is to find values of x that satisfy either x < ∘⅗⁄3 or x ≤ ∘⅗/13.
Explanation:To solve the equations −9x+2>18 OR 13x+15≤−4, we need to treat them separately as two different inequalities.
For the first inequality, subtract 2 from both sides to get −9x > 16, then divide by −9 to isolate x, which gives us x < ∘⅓⁄9 or x < ∘⅗⁄3.
For the second inequality, subtract 15 from both sides to get 13x ≤ −4 − 15 or 13x ≤ −19. Finally, divide by 13 to isolate x, leading to x ≤ −⅓⁄13 or x ≤ ∘⅗/13.
Therefore, the solution to the system of inequalities is any x that satisfies at least one of these conditions: x < ∘⅗⁄3 or x ≤ ∘⅗/13.

how do you write 996 as a fraction, mixed number, or whole number in simplest form?
To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."
A proper fraction is a fraction that has a lower number in the numerator and a higher number in denominator, such as the fraction three-fourths. An improper fraction is the inverse of this, which entails the higher number in numerator and lower number in the denominator, like 5/3. A mixed number is a whole number with a fraction, such as 1 3/4.
To convert the mixed number 1 3/4, one has to multiply the denominator 4 by the whole number 1 that gives 4, add this 4 to the 3 in the numerator to get 7 and place 7 over the denominator to find the improper fraction 7/4. In this case, this is the lowest form for this mixed number. However, if the mixed number is 6 4/6, then this converts to the improper fraction 40/6. One can divide the numerator and denominator of 40/6 by 2 to find that 20/3 is the lowest form for the mixed number 6 4/6.To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction.

Tracey is looking at two different travel agencies to plan her vacation. ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. M and N travel offers a plane ticket for $350 and a rental car for $33 per day. What is the minimum number of days that Shirley’s vacation should be for M and N Travel to have the better deal?
Shirley/Tracey has to stay at least 10 days for the M and N to cost less
Answer:
10 days.
Step-by-step explanation:
Let d represent number of days.
We have been given that ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. The total cost of travelling x days using ABC travel company would be [tex]39x+295[/tex].
We have been given that M and N Travel offers a plane ticket for $350 and a rental car for $33 per day. The total cost of travelling x days using M and N travel company would be [tex]33x+350[/tex].
To make M and N travel the better deal, we will set an inequality, where total cost of x days using ABC travels is greater than M and N travels as:
[tex]39x+295>33x+350[/tex]
[tex]39x-33x+295>33x-33x+350[/tex]
[tex]6x+295>350[/tex]
[tex]6x+295-295>350-295[/tex]
[tex]6x>55[/tex]
[tex]\frac{6x}{6}>\frac{55}{6}[/tex]
