You have a grade of 85 & 90

faltersainse [42]

Answer:

You need to get a 95 on the next test to have a 90 grade average.

Step-by-step explanation:

(85 + 90 + n)/3 = 90

<u>Step 1: Multiply both sides by 3</u>

(85 + 90 + n)/3 * 3 = 90 * 3

85 + 90 + n = 270

<u>Step 2: Subtract 85 from both sides</u>

85 + 90 + n - 85 = 270 - 85

90 + n - 90 = 185 - 90

n = 95

Answer: You need to get a 95 on the next test to have a 90 grade average.
