Question

Joaquin receives $0.40 per pound for 1-99 pounds of aluminum cans. He receives $0.50 per pound if he recycles more than 100 pounds. Is the amount of money he receives a function of weight of the cans he recycles?

Answer 1

Yes. It is a piecewise function.

If 1<x<99, f(x)=0.4x

If x>100, f(x)0.5x
