A single inequality needed

Question

Fatoumata and her children went into a movie theater and will buy drinks and candies. Each drink costs $5.50 and each candy costs $3.75. Fatoumata has a total of $65 to spend on drinks and candies. Write an inequality that would represent the possible values for the number of drinks purchased, d, and the number of candies purchased, c.

Answer 1

d = no. drinks @ $5.50 (Wow!) Cost of drinks = 5.50d

c = no. candies @ $3.75 Cost of candy = 3.75c

5.50d + 3.75c ≤ 65

Answer 2

Let d = number of drinks

Let c = number. of candies

5.50d + 3.75c <= 65
