## anonymous one year ago Fidel needs an average of at least 75 on his three history tests. He has already scored 70 and 85 on two tests. What is the minimum grade Ted needs on his third test?

The average (75) is the sum of the numbers (70 + 85 + n) divided by the amount of numbers (3). $\frac{ 70+85+n }{ 3 }=75$
