AND
THE dimensions of rectangular parking lot are 330ft by 480ft
What is the area of the parking lot in square yards?

We need to find the price of one item.
50 for $1.25 = 1.25 / 50 = $0.025 each
100 for 2.25 = 2.25 / 100 = 0.0225 each
Do the others the same way. What do you find is the best price?
330ft = 330/3 = 110 yards
480 ft = 480/3 = 160 yards
A = L * W
A = ? 
thanks

You're welcome.

i didn't understand the second question

You find the area of a rectangle by multiplying the length times the width.
In this problem, I converted feet to yards. Multiply the length times the width.
