Question

You score 63 out of 75 on your first test. after your second test your teacher tells you your test average is 88%. the second test has 75 points possible. what percent did you receive on the second test?

Answer 1

Combined, both tests are comprised of 150 total points. You scored 63 on the first and
`x` on the second, and this nets you an average of 88%.

You have


`(63+x)/(150)=0.88\implies 63+x=132\implies x=69`
