Question

Your math test scores have been: 73, 86, 91,88 Just from these scores, your current grade is 84.5 You just scored a 67 on the last test. What is your new grade?​

Answer 1

`81`

Explanation:

The average of a set of
`n` values is equal to the sum of the values in that set divided by
`n`.

Therefore, the average of your 5 scores is equal to
`(73+86+91+88+67)/(5)=\boxed{81}`. Since evidently your grade is represented by the average of all your scores, your new grade is 81.
