Johnny can buy two 8-foot pieces of 2" by 4" lumber at $2.60 each, or three 6-foot pieces for $1.92 each. which is the better buy per foot?

c

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
