Question

A manufacturing plant can produce 52 flip flops or 25 tennis shoes per hour. Let f represent the hours spent producing flip flops and t represent the hours spent producing tennis shoes. What is the constraint equation if the plant can only produce shoes for 12 hours a day?

Answer 1

f + t = 12 is the answer because it is saying to let the variables represent the hours spent producing shoes. And the hours spent is 12, so f+t is the amount of shoes (represented by variables) the factory can make in 12 hours.
