    For the first one, we'll plug in the numbers in the set to see which ones will work.

    So can you get the average of 45,48, and 46, and tell me what you get? :)

    Right. Now we want the average of 4 tests to be 60. So we need the average to go up 10. So we can represent this with \[\large \frac{45+48+46+x}{4}=60\] Now we need to get x alone
