Question

Jace's class takes 5 tests per term. He currently has scores

of 75, 90, 80, and 92. What score does he need to get on his
5th test in order to have an average of 85?

Answer 1

Jace needs a score of 90 on his 5th test to have an average of 85.

Step-by-step explanation:

Jace's class takes 5 tests per term. To find the score he needs on his 5th test to have an average of 85, we can use the formula:

Average = (Sum of scores)/(Total number of tests)

First, we need to find the sum of Jace's current scores: 75 + 90 + 80 + 92 = 337

Next, we substitute the values into the formula: 85 = (337 + x)/5

By solving for x, we find that Jace needs a score of 90 on his 5th test to have an average of 85.
