Kyle's scores on his first five tests were 86, 80, 85, 75, and 84. what score must he get on the next test so that his average will be exactly 85?

The answer is (on his next test he must score a 100)

The formula for average is to add all the numbers up then divide it by the amount of numbers so to solve it would be (86+80+85+75+84+100)=(510/6)=85

(86+80+85+75+84+100)=(510/6),thus the answer will be 100,he will score 100 on his next test
