# 20% of a student's final grade for each semester comes trom the final semester exam. The average of each quarter is worth 40%. What would a student need to make on the exam if she wanted to have a semester average of at least 92 and the first quarter average was 93; the second quarter's average was 89 ? (The final average will be rounded up to the nearest whole number)

Question:

A
96

Explaination

Each quarter's grade is worth 40% and the final exam is worth 20%.

Use the following equation: 93 x 40% + 89 x 40% + FG x 20% = 92, where

FG is the final exam.

37.2 + 35.6+ 0.2(FG) = 92

0.2(FG) = 19.2

FG 19.2/0.2 = 96
