A store sells beans for 80 cent per pound.

A. Graph The proportional relationship that gives the cost y in dollars of buying x pounds of beans.

B. Write an equation of the form Y=kx to represent this relationship

Answer 1

0.80X = Y

Explanation:

Given that a store sells beans for 80 cent per pound to determine the equation that graphs the proportional relationship that gives the cost Y in dollars of buying X pounds of beans, the following mathematical reasoning must be performed:

Cost of each pound of beans = 0.80

0.80 x quantity (X) = Total cost (Y)

0.80X = Y

Thus, if 5 pounds of beans were purchased, the equation would operate as follows:

0.80 x 5 = Y

4 = Y
