HELP

Answer 1

Explaination:

First your going to want to multiply the amount of days by how much money a school lunch costs:

1.80 x 20 = $36

The next step you will minus the amount spent by the beginning balance on your lunch account:

42 - 32 = $6

Then you will want to add the amount of money it costs for a snack untill it adds up high enough where it is close to the amount of money left (or you cant add any more):

0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 = $5.95

You then count the times you added 0.85 which would be 7 times.

You can also multiply 0.85 by 7 to shorten it up:

0.85 x 7 = $5.95

This would leave $0.05 left.

Final answer:

After 20 days you would have 7 snacks total.
