The average for lynn's two test scores must be at least a 93 to make an a. lynn got an 88 on her first test. what scores can she get on her second test to make an a in the class?

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 =

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.  

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
