Question

Mrs. Ventura charges $25 for a basic cake that serves 12 people. A larger cake costs an additional $1.50 per serving. The total cost can be given by y = 1.5x + 25, where x represents the number of additional slices. What does the slope represent? a. the cost per additional slice c. the charge for 15 people b. the charge for the basic cake d. the cost of Mrs. Ventura’s ingredients

Answer 1

Y must be in dollars. 25 is in dollars and 1.5 is dollars divided by serving. You have to make 1.5*x be in dollars so you have to get rid of the servings in the denominator. So x must be what?

Answer 2

i would say c, the charge for 15 people?

Answer 3

X is the number of servings.

Answer 4

so a?

Answer 5

Yes, because you have

Dollars/servings multiplied by x

To make the units dollars, you must multiply by servings.
