2. Seth’s bank charges $5 a month to maintain a
checking account and $0.50 for each check Seth
writes. Last month, Seth paid a total of $6.50 in
checking account fees. How many checks did he
write?
A 1 C 3
B 2 D 4
Let x be the number of checks Seth wrote.
The total amount he paid is the sum of the monthly maintenance fee and the fee per check:
$5 + $0.50x = $6.50
Subtracting $5 from both sides:
$0.50x = $1.50
Dividing both sides by $0.50:
x = 3
Therefore, Seth wrote 3 checks.
The answer is (A) 3.
