Question

What is the function rule that represents the cost (c) of frozen yogurt as a function of the weight (w) in ounces at the rate of $2.65 per ounce?

a) c = 2.65w
b) c = 2.65 + w
c) c = w/2.65
d) c = w - 2.65

Answer 1

The function rule that represents the cost (c) of frozen yogurt as a function of the weight (w) in ounces at the rate of $2.65 per ounce is c = 2.65w.

Step-by-step explanation:

The function rule that represents the cost (c) of frozen yogurt as a function of the weight (w) in ounces at the rate of $2.65 per ounce is c = 2.65w.

Since the rate is $2.65 per ounce, the cost (c) is obtained by multiplying the weight (w) in ounces by the rate ($2.65).

For example, if the weight of the frozen yogurt is 10 ounces, the cost would be calculated as c = 2.65 * 10 = $26.50.
