Question

Jack’s average in Math for the first nine weeks was an 88. His second nine weeks average decreased 12.5%. What was his average for the second nine weeks?

Answer 1

Answer: 77

Step-by-step explanation: 88 times 12.5% and then you get 11 then you do 88 minus 11 and 77 is your answer.

Answer 2

All you have to do is minus 12.5 from 88.

So:

88-12.5=75.5

So the answer is 75.5%
