A student earned scores of 85, 83, 90, 94, 88 and 84 on the first six tests in a biology class. What score is needed on the seventh test to produce an 86 average?
Answered by Damon
(85+83+90+94+88+84+x)/7 = 86
Answered by Mimi
Do I add them together, have the answer and then divide by 7 ?
Answered by Damon
ok here
(524+x)/7 = 86
524+x = 602
x = 78
