Evelyn Wood · Answer 1

H = number of hamburgers

c = number of cheeseburgers

There are 100 burger buns, therefore

h + c ≤ 100 (1)

The amount raised by selling h hamburgers and c cheeseburgers to make at least $80 is given by

3.00h + 3.50c ≥ 80 (2)

The problem to be solved is represented by the system of inequalities (1) and (2).
