69. The O'Brien's had $400.0 in a special checking account for installment payments.
After paying $40.00 a month for three months
and $20.00 a month for two months. How
much was left in the account?​

Hello :D

$40.00 x 3 = $120.00

$20.00 x 2 = $40.00

$120.00 + $40.00 = $160.00

$400.00 - $160.00 = $240.00

There is $240.00 left in the account.

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7
