Question

Kayden and his children went into a bakery and will buy donuts and cookies. Each donut costs $1 and each cookie costs $0.75. Kayden has a total of $15 to spend on donuts and cookies. Write an inequality that would represent the possible values for the number of donuts purchased, d, and the number of cookies purchased, c.

Answer 1

Answer: d+ 0.75c ≤ 15

Explanation:

Let d = number of donuts purchased, c = number of cookies purchased .

Given: Each donut costs $1 and each cookie costs $0.75.

Cost of d donuts = d

Cost of c cookies = 0.75c

Total cost = d+ 0.75c

Budget = $15

As per given, Total cost ≤ budget

⇒ d+ 0.75c ≤ 15

Hence, the inequality that would represent the possible values for d and c :

d+ 0.75c ≤ 15
