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 b. the charge for the basic cake c. the charge for 15 people d. the cost of mrs. ventura’s ingredients

graph equation in the form of y = mx + c

where x and y are variables, m - slope and c - intercept

intercept is a fixed cost.

In this case its $25. For a basic cake this cost is charged irrespective of the number of slices needed. Therefore its fixed

for every extra serving she charges $1.50.

therefore the total cost is 25 dollars anyway and an additional 1.50 times the number of additional slices needed.

the slope is the coefficient of x in

y = 1.5x + 25

slope = 1.5

and 1.5 is the cost per additional slice

answer is A.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

found it xd it ok yt
