Question

Ebony earned scores of 71 , 70, 87, 97 , and 82 on five math tests. Determine her

score on the sixth test if her average for the six tests was 83? Enter your answer as a
whole number

Answer 1

The answer is 91

Explanation:

Average Marks = (Total Marks) ÷ Total Tests

83 = (71 + 70 + 87 + 97 + 82 + x) ÷ 6

83 × 6 = 407 + x

498 = 407 + x

x = 498 - 407

x = 91
