Question

on his first 5 tests, che averaged 92 points. on his next 3 tests hw scored 94, 85, and 85 points. what was his average for all 8 tests?

Answer 1

Answer:

90.5

Step-by-step explanation:

To get the average, we must add all the values and divide the sum by the amount of them:

1. Add (92*5), 94, 85, 85 = 181
2. Divide by the number of grades (8): 181/8

The answer will be 90.5, which is his average through all eight tests.

To do this in one step:

$\frac{(92*5)+94+85+85}{8} = 90.5$
