Andre is in charge of cooking broccoli and zucchini for a large group. He has to spend all $17 he has and can carry 10 pounds of veggies. Zucchini costs $1.50 per pound and broccoli costs $2 per pound. One graph shows combinations of zucchini and broccoli that weigh 10 pounds and the other shows combinations of zucchini and broccoli that cost $17.

Name one combination of veggies that weighs 10 pounds but does not cost $17.
Name one combination of veggies that costs $17 but does not weigh 10 pounds.
How many pounds each of zucchini and broccoli can Andre get so that he spends all $17 and gets 10 pounds of veggies?

Answer 1

To spend all $17 on 10 lbs of veggies, you need
z+b = 10
1.50z + 2.00b = 17.00
That comes to 6 lbs of zucchini and 4 lbs of broccoli

I think now you can come up with answers for the other two questions
