x-\ width\\
y-\ length\\
4x=y\\
(y+4)(x-1)=60\\
(4x+4)(x-1)=60\\

4x^2=56\ \ | divide\ by\ 4\\
x^2=14\\
x=\sqrt{14}\\
y=4\sqrt{14}\\\\

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordere
Ronch [10]

Part A

We have x = 4 and y = 3 paired up together.

This says that 4 pounds of potatoes cost $3

The price per pound (aka unit price) is y/x = 3/4 = 0.75 dollars = 75 cents.

Answer: 75 cents per pound

========================================

Part B

The ordered pair (8,6) means x = 8 and y = 6 pair up together.

So in this case, 8 pounds of potatoes cost $6.

notice how y/x = 6/8 = 3/4 = 0.75 dollars = 75 cents here as well. So we get the same unit cost.
