Answer:

90.5

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:


((92*5)+94+85+85)/(8) = 90.5
