Question

Jen's test grades for this term are 85,92, and 95. She wants to have a test average of at least 90 for this term, and she will have one more test. What is the lowest score that she can get to have a test average of at least 90?

Answer 1

Explanation:

(85+92+95+x)/4

=90

(272+x)/4

=90

90×4=360

272+x=360

x=360-272=88

so it's the lowest score
