matt has the following grades in his science class: 92, 85, 96, and 100. of he has one more test to take in the class, what score must he have to make an average of 90?
Answered by anonymous
To find the average, add up all numbers and divide by how many numbers there are.
(88+84+92+x)/4=90
88+84+92+x=90*4
264+x=360
x=96.
The student has to make a 96.
