Question

Quizplus · Accepted Answer

To keep an average of 80 or greater after three tests, the total score from the three tests must be at least 240 (since 80 * 3 = 240). Jim has already scored 61 and 82, which sum to 143. Subtracting this from 240 gives 97, so he must score at least 97 on his third test.
