Answer:
Johnny needs to score 98 on third test to raise average to 94
Step-by-step explanation:
Given that average of two tests is 92.
The score of next test has to be found that means there will be a total of 3 tests.
The average will be:
[tex]Avg = \frac{test1+test2+test3}{3}[/tex]
It is also given that he has to raise his average to 98
We have to use the average formula for finding the third value
So,
[tex]94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282 = 184+test3\\test3 = 282-184\\test3 = 98[/tex]
Hence,
Johnny needs to score 98 on third test to raise average to 94
