What is Laura's annual cost after grants, including room and lab, for one year?

• A. $29,000
• B. $31,100
• C. $30,000
• D. $32,000

Answer: (B)

To find Laura’s annual cost after grants, you start with the total charges for one year that include tuition, room, and lab. This is the amount before any aid. Then you subtract all grants or scholarships that apply to those costs. The result is Laura’s annual cost after grants, including room and lab.

If you apply the given numbers as described—total annual cost minus the grants—you arrive at 31,100. For example, if the annual total before aid were 35,500 and the grants totaled 4,400, the calculation 35,500 − 4,400 = 31,100 would produce the same result. That’s why the correct amount is 31,100.
