Question

Lee scored 91 points on a math testOn the next test, she scored 13 fewer pointsOn the third test, she scored 92What is the difference between Lee's highest and lowest scores?

Answer 1

14 points

Explanation:

The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.

The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.

The difference between Lee's highest and lowest scores is:

92 - 78 = 14 points
