David estimates that he will have expenses totaling $24,870 for one year of college. he will receive $7,560 in grants. how much will david have to contribute each semester during this year?

The answer is $8,655.

We will deduct the grant of $7,560 from his total expenses of $24,870 so we will get $17,310 which is the amount he has to contribute per year. Since there are two semesters in a year, we will divide this amount by 2 and we will get $8,655 which is the amount he has to contribute for one semester.

Expenses : $24,870
Grant        : $ (7,560)
                   $ 17,310
# of sem      ÷      2
                   $ 8,655
