Answer:
$6.80
Explanation:
First, we know that Kevin has $25.
Next we know that Kevin has $2.20 less than 4 times the amount molly has in her account.
This means that 25+2.20=27.20 is four times molly's total checking account amount.
To find how much is in Molly's account, lets divide $27.20 by 4.
27.20/4=6.8
6.8 is $6.80. This is how much is in Molly's account.
