Question

Johnny scored an 82 on his review quiz and a 94 on his actual test 1. Use an absolute and relative change to compare his actual test score to his review score.

Answer 1

Explanation:

To compare Johnny's actual test score to his review score, we can use absolute and relative change:

Absolute change = actual score - review score

Relative change = (actual score - review score) / review score * 100%

Using Johnny's scores:

Actual score = 94

Review score = 82

Absolute change = 94 - 82 = 12

Relative change = (94 - 82) / 82 * 100% = 14.6%

Therefore, Johnny's actual test score increased by an absolute amount of 12 points and by a relative amount of 14.6% compared to his review score.
