Question

sherman hopes to get at least a 90 average on his science test. he has one more test before the end of the school year. his past test scores are 79,94,and 92. what is lowest score sherman can get on his final test and reach his goal?

Answer 1

93 if rounding from 89.5 to 90 counts, if not then 95

Explanation:

The first thing you do is add 92+94+79=265

then divide by 3 265/3=88 1/3

so his score has tp be higher than an 88 so lets try 90

92+94+79+90=355: 355/4=88.75

so higher lets try 94

94+94+92+79=359

359/4=89.75
