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

Answer:

0.80X = Y

Step-by-step 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
