Question

A frozen yogurt store charges based on how many ounces of yogurt, x, customers put in their cups. The store also charges a flat price for unlimited toppings. The function for the cost of a cup of yogurt with toppings is

f(x)=0.37x+1.50. What does this function indicate?
A) Each ounce of yogurt decreases the cost by $0.37.
B) Each ounce of yogurt increases the cost by $0.37.
C) Each ounce of yogurt decreases the cost by $1.50.
D) Each ounce of yogurt increases the cost by $1.50.

Answer 1

The function f(x) = 0.37x + 1.50 indicates that each ounce of yogurt increases the cost by $0.37, with a flat charge of $1.50 for unlimited toppings.

Step-by-step explanation:

The function f(x) = 0.37x + 1.50 indicates the cost of a cup of yogurt with toppings at a frozen yogurt store. Here, x represents the number of ounces of yogurt. The coefficient of x, which is $0.37, tells us the cost per ounce of yogurt. Therefore, for each ounce of yogurt, the cost increases by $0.37. The +1.50 in the function is the flat price for unlimited toppings, which is added to the total cost regardless of the amount of yogurt. Given the options presented, the correct answer is B) Each ounce of yogurt increases the cost by $0.37.
