Inequality in Two Variable

Question

On her last 3 activities in Math 8, Jaja has scored 86, 89 and 93. What score does she need to get on her next test if she wants the average of all four tests to be higher than a 92?

Answer 1

86+89+93+X > 92(4) = 368

x = 368 - 268 = 100

even with a 100, she won't get higher than 92.

but she would get exactly 92 as the average of all 4 tests

IF the test has any extra credit she could get higher than 92, is she got 101 or more

or "just" 100.0001 would push her over 92
