Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26
If the line is parallel, it has the same slope. So now just find the y intercept and put it into slope-intercept form
Answer:

Step-by-step explanation:

3 x 8 = 24
3 x -2 = -6

The total would be $4.68. It is $0.78 for 0.4 of a pound, and you multiply $1.95 two times aqnd add that to the $0.78
