Draw your answer below:

Answer 1

A) 5/2 = 2.50, it costs $2.50 per pound

B) yes because 7.50 / 3 = 2.50 as well

C) weight would be on x-axis and cost on the Y axis

D) draw a graph and put the dots on (2,5) and (3,7.50) and draw a straight line

E) 2.50 *5 = $12.50, multiply cost per pound by pounds.
