Not gonna give an answer, sorry. Instead, I'll show you a similar example so you can be able to solve it.
An average test score is the sum of all the scores on an assessment divided by the number of test-takers.
For example, if three students took a test and received scores of 69, 87, and 92.
These numbers would be added together and then divided by three to get an average of 82.6.
I hope you know what to do now.

Step-by-step explanation:
(82 + 95 + 90 + 87 + x) / 5 = 95 Add like terms on the left
(354 + x) / 5 = 95 Multiply by 5
354 + x = 95 * 5
354 + x = 475 Subtract 354 from both sides
x = 475 - 354
x = 121
On the first step, you need to add an x which represents the score he needs. You divide by 5 because that's how many scores there and and the 5 gives you an average.
