Answer:
$8
Step-by-step explanation:
The problem says
He wrote 10 checks in April. There is no fee for the first 6 checks written in one month after that each check is $0.75. he also has a $5 monthly service charge
So that means 4 of the checks have the $0.75 fee
add 0.75 4 times and you get $3
plus the $5 monthly fee makes it $8
tell me if i'm wrong :)
