Bens test grades this term is 85,92,95 he wants a test average of at least 90 this term and he has to take one more test what is the lowest score to get an average of. 90

Answer 1

To get an average of 90, Ben will need to have a total score of:

(85 + 92 + 95 + x) / 4 = 90

Multiplying both sides by 4:

85 + 92 + 95 + x = 360

Simplifying:

x = 88

So Ben will need to get at least an 88 on his next test to achieve an average of 90 for the term.
