Question

Five students took and algebra test. The average score was 84. The four scores were 96, 68, 79, and 85. What score did the fifth student get?

Answer 1

(96+68+79+85+x)/5 = 84
(96+68+79+85+x)= 84*5
328+x =420
so, x= 92

Answer 2

so fifth score is 92

Answer 3

remember that the average is the sum of the terms divided by the number of the times.
Since the number of terms is 5. we have
84=total/5
thus total=420
and 420= 96+68+79+85+x = 328+x
and so x=92

Answer 4

thank you everyone. :)
