83, 88, and a 91. what does she need to make on her 5th test to get a 90 average

She needs to get 94 in the fifth test.

Step-by-step explanation:

Peyton wants to get an A in her Chemistry class this semester. Her first 4 tests were 94, 83, 88, and 91.

She has to get an average mark of 90 and to do that let us assume, she has to get x in the fifth test.

So, mathematically

⇒ 356 + x = 90 × 5

⇒ 356 + x = 450

⇒ x = 94

Therefore, she needs to get 94 in the fifth test. (Answer)
