Felix scored 52 and 64 on his first two test in Sociology 212. What must he get on the third test to get an average of the three

Pie

Answer:

Felix's third test score must be greater than 94

Step-by-step explanation:

Felix scores on Sociology 212 tests:

1st test - 52

2nd test - 64

3rd test - x

Find the average of Felix's scores:

$\text{Average}=\dfrac{\text{The sum of all scores}}{\text{The total number of scores}}\\ \\\text{Average}=\dfrac{52+64+x}{3}$

An average of the three test must be above 70, this means

$\text{Average}>70\\ \\\dfrac{52+64+x}{3}>70$

Solve this inequality. First, multiply it by 3:

$52+64+x>210\\ \\x>210-52-64\\ \\x>94$
