Answer:
Lynn must score 98 in her second test to make an Average of 93 and get an A.
Solution:
Required average of test score by Lynn’s to make an A = 93
Number of tests for which average is calculated = 2
Score of Lynn in first test = 88
let’s assume the score required by Lynn in second test to make an A = x.
Average of test score = [tex]\frac{Total score of all test}{number of tests}[/tex]
[tex]93 = \frac{(88 + x )}{2}[/tex]
186 = 88 + x
x = 186 – 88 = 98
Hence Lynn must score 98 in her second test to make an Average of 93 and get an A.
