Given:

Joe bought a pumpkin that cost 10 cents more per pound than his sister's

The two pumpkins weighed 20 pounds,

Joe paid $3.52

His sister paid $0.48.

To find:

How many pounds did Joe's pumpkin weigh?

Weight of Joe + Weigh of his sister = 20

By subtracting both side by

By cross multiplication:

By dividing both side by 199

cost of per pound pumpkin bought by Joe's sister = = $0.20

cost of per pound pumpkin bought by Joe =

Joe's pumpkin weigh = cost divided by rate of pumpkin
