Final answer:
Adding up tuition, transportation, books and fees, and other expenses, and then subtracting the grant, Joaquin will need to contribute a minimum of $13,035 annually to his education costs if he lives at home.
Step-by-step explanation:
The student has presented a scenario involving the prediction of annual college costs and the impact of a grant on those expenses. To calculate the minimum amount Joaquin will need to annually contribute to his education assuming he lives at home, we first need to add up all the expenses except room and board, as he won't incur that expense. This includes tuition, transportation, books and fees, and other expenses.
Tuition: $9,450
Transportation: $2,680
Books and Fees: $1,875
Other: $930
Total without Room and Board: $14,935
Next, we subtract the grant amount ($1,900) that Joaquin received from the total:
Total minus Grant: $14,935 - $1,900 = $13,035
Therefore, the minimum amount Joaquin will need to contribute to his education annually, while living at home, is $13,035.
