Question

Julie wants to have a 90 average in her math class at the end of the year. She is trying to determine what she needs to make on her final exam for this to work. Everything is weighted equally and she currently has a 85 for her quiz average, a 80 for her homework average, a 92 for her test average, and a 98 for her project average. What does she need to make on her final exam for her to end up with a 90 in the class?

Answer 1

(85 + 80 + 92 + 98 + x)/5 is 90

Answer 2

Julie will need a 95 in her final exam.

Explanation:

Julie wants to have a 90 average in her math class at the end of the year.

Everything is weighted equally and current scores are = 85,80,92,98

Let she needs to get x marks in final exams to get average of 90.

Hence, we can show this as:
`(x+85+80+92+98)/(5)=90`

=>
`(x+355)/(5)=90`

=>
`x+355=450`

=> x = 95

Therefore, Julie will need a 95 in her final exam.
