After 4 tests, Amanda's average score was 88. What score must she earn on her next test to have a 5-test average?
Answered by Ms. Sue
Whatever score she makes, she'll still have a 5-test average.

Does she have a specific average she'd like to achieve?
Answered by Noa
Sorry specific average after 5 tests should be 90.
Answered by Reiny
(4(88) + x)/5 = 90
352 + x = 450
x = 98
