Answer:
$ 800
Step-by-step explanation:
Parking slot is in the shape of parallelogram.
base = 3 m
Height = 6 2/3 m
Area = base * height

Cost of paving the parking spot = 20 * 40
= $ 800
5x + 3y= 8.50
3x + 2y= 5.25
Lydia is the first equation. She bought 5 pounds of apples which is x and bought 3 pounds of bananas which is y. Basically, remember each banana and apple weighs a price per pound. We don't know the price so we just put an x. This is the same for the second equation
