Question

Randy had grades of 85, 92, 96, and 89 on his last four math tests. What grade does he need on his next test to have an average of 92?

Answer 1

Randy needs to score 98 on his next math test to achieve an average of 92 across all five tests.

Step-by-step explanation:

To solve this problem, we need to calculate the average of Randy's math test scores and determine what score he needs on his fifth test to achieve an overall average of 92. Randy's current grades are 85, 92, 96, and 89.

The formula for an average is the sum of the values divided by the number of values. To have an average of 92 after five tests, the sum of all five test scores should equal 92 multiplied by 5:

92 * 5 = 460

We now add up Randy's four test scores:

85 + 92 + 96 + 89 = 362

To find the score Randy needs on the fifth test, we subtract the sum of his current scores from the desired total:

460 - 362 = 98

Therefore, Randy needs to score 98 on his next test to have an average of 92.

Answer 2

Maybe fifth grade or sixth from my understanding.
