Going into final, which will count as three test, Monica has test scores of 76, 90, 94, and 88.
What score does Monica need on the final exam in order to have an average score of 90?
:
let x = the final score
Since the final counts as 3 tests, we will treat it like you had 7 scores.
= 90
348 + 3x = 7(90)
3x = 630 - 348
3x = 282
x = 282/3
x = 94 is the required score
