To help the environment and make some extra money, Barbara takes her empty
cans to the Cash Not Trash recycling shop. The shop pays cash based on the total
weight of the cans Barbara brings in for recycling. There is a proportional
relationship between the weight (in pounds) of the cans Barbara brings into the
shop, x, and the amount (in dollars) the shop pays Barbara, y.
The equation that models this relationship is y = 0.25x.
How much money would the shop pay Barbara for 16 pounds of cans? Write your answer as a
whole number or decimal.
