Jason is buying grapes for a picnic. Green grapes cost $2 a pound and red grapes cost $3 a pound. He plans to buy at least 4 pounds of grapes and spend no more than $20. List two possible combinations of the number of pounds of green and red grapes he could buy.

Green Grapes = = 4

Red Grapes = = 4

Green total = $8

Red total = $12

Total Cash = $20

Total Pounds = 8

That's one solution

Another would be this / / / / / /

Green Grapes = = 0

Red Grapes = = 4

Green Grapes = $0

Red Grapes = $12

Total Money = $12

Total Pounds = 4

Sounds a little simple ... ?
