Question 581721
This year in math the teacher will be giving 5 tests, each scored out of 100. If Heather wishes to get an A+ average (90 or above), what is the lowest possible score she can receive on a test?
---
To get an average of 90 she can miss a total of 5*10 = 50
points in the 5 tests. (She needs 450 points in the 5 tests)
---
The lowest test score she can get is 50 (she will need 100
on 4 of the tests).
Cheers,
Stan H.
