Answer:

it would cost $34.50 to purchase 7.5 lbs of walnuts.

Answer:

$34.50

Step-by-step explanation:

First find out how much 1/4 of a lb will cost.

3.45/3= 1.15

This is the cost for only 1/4 a lbs of chopped walnuts. Take this number and multiply it by 4 to find how much it would cost for 1 whole pound of walnuts.

1.15x4= 4.60

It costs $4.60 for a whole pound of walnuts. If you are trying to find how much it costs for 7.5 lbs, then multiply 4.60 by 7.5.

4.60x7.5= 34.5

For 7.5 lbs of walnuts will cost $34.50
