Question

Jay Low received scores of 87 and 98 on his first two exams of the grading period. At least what score must jay earn on the next exam for the test average to be at least a 93 for the grading period?

Answer 1

(87 + 98) / 2
185 / 2
92.5 is his current grade

if we try 90 first
(185 + 90) / 3
91.7 isn't enough

92
(185 + 92) / 3
92.3 isn't enough

94
(185 + 94) / 3
93

He needs to get at least a 94 on his next quiz to end with a 93 in the class
