A student is trying to calculate his semester average. He knows that his test average is an 85, his quiz average is a 79, homework is a 92, and classwork is a 95. If tests and quizzes are worth 30% each, and homework and
classwork are worth 20% of his overall average, what is his average? Round to the nearest tenth.

The student's average is 86.6.

Step-by-step explanation:

Since a student is trying to calculate his semester average, and he knows that his test average is an 85, his quiz average is a 79, homework is a 92, and classwork is a 95, if tests and quizzes are worth 30% each , and homework and classwork are worth 20% of his overall average, to determine what is his average the following calculation must be performed:

(85 x 3 + 79 x 3 + 92 x 2 + 95 x 2) / 10 = X

(255 + 237 + 184 + 190) / 10 = X

866/10 = X

86.6 = X

Therefore, the student's average is 86.6.
