Question

On mr robinsons last history test for this marking period. the average score was 98. Fourty students took the test and 39 students scored 100. What was the score of the student who did not score 100 on the test?

Answer 1

20

Explanation:

`\displaystyle (39(100)+x)/(40)=98\\\\3900+x=3920\\\\x=20`

Therefore, the remaining student scored a 20 (which sounds weird, but I'm going with it).
