He received a grant for $1,900. What is the minimum amount Joaquin will need to contribute to his education annually if he chooses to live at home?

$13035 will be needed.

Explanation:

In order to calculate Joaquin’s out of pocket cost for college you need to first calculate what the total cost for college is. In this example, he will need to pay all of the listed fees except room and board if he chooses to live at home. The total fees after not including the expense of room and expense of board is calculated to be as $14,935. The amount of grant that is received is $1900 that needs to be subtracted from the annual cost.  

Thus, $14935 minus $1900 = $13035

if you use only 25 for your entertainment and only 200 for the groceries that you really need and take out the 50 per month for the computer then that should be enough
