1. use the graph to answer the questions. (a) write an equation to represent the cost of the strawberries. (b) write an equation to represent the cost of the blueberries. (c) which fruit is cheaper? explain your answer.

Step-by-step explanation:

(a)  the cost of the fruit in $ per lb = slope of the line

For strawberries consider the point at the end of the ' strawberry' Arrow. This corresponds to

a cost of $10 ( the height of the vertical axis) and a weight of the strawberries ( the corresponding point on x axis)

so the lope  is  10/5 = 2   That is $2 per lb of strawberries

Cost = 2w  where   w = weight of strawberries in pounds

(b) in the same  way cost of each lb of  blueberries = 10/7 =  $ 1.43

cost =   10w/7    where w = weight of blueberries in lbs.

c)    blueberries are cheaper ( $1.43 / lb against  %2 per lb for strawberries)
