Answer:

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

Step-by-step 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
