Darian's annual expenses at an out-of-state public four-year university include tuition $18,900, room/board $7,650, books/fees $1,475, and other expenses $2,350. If he receives $7,500 in grants each year, what is the minimum amount he should contribute for four years?

• A. 100,000
• B. 80,000
• C. 76,000
• D. 91,500

Answer: (D)

To figure out the four-year amount, find the yearly net cost by subtracting the annual grants from the yearly expenses, then multiply by four. Annual expenses: 18,900 + 7,650 + 1,475 + 2,350 = 30,375. Subtract grants: 30,375 − 7,500 = 22,875 per year. Over four years: 22,875 × 4 = 91,500. So, the minimum amount he should contribute for four years is 91,500.

To figure out the four-year amount, find the yearly net cost by subtracting the annual grants from the yearly expenses, then multiply by four.

Annual expenses: 18,900 + 7,650 + 1,475 + 2,350 = 30,375.

Subtract grants: 30,375 − 7,500 = 22,875 per year.

Over four years: 22,875 × 4 = 91,500.

So, the minimum amount he should contribute for four years is 91,500.
