Ted need to score at least 70 on his three tests, he has scored already 85 and 60 on two test, what would be the third test score?

First test: 85

second test: 60

third test: x = ?

total: 70

(85 + 60 + x) / 3 > = 70

You have to divide this by the number of tests Ted will take (in this case 3).

145 + x > = 70 * 3

x > = 70 * 3 - 145

x > = 210 - 145

x > = 65

Ted has to score at least 65 on his third test.
