Javier had $305 in his bank account. His bank charges a monthly fee of $7.50. If he makes no other deposits or withdrawals, how much money is in Javier's account at the end of three months?
Enter your answer in the box.

$282.50

Step-by-step explanation:

He will be charged $7.50 for 3 months, which is a total of 7.5 * 3 = $22.50.

Subtract this from the amount in his account to find the amount of money he has at the end of the three months:

305 - 22.5 = 282.5

The answer is therefore $282.50.
