Question

Before your test you earn 10 point extra credit to be added to your test grade. If your goal is to make from a 85 to 105 after the 10 extra credit points are added, what do you have to make on a test before extra credit

Answer 1

If you want anywhere from an 85 to 105, then you subtract those 10 free points, and need to make anywhere from a 75 to 95.

Answer 2

You have to subtract them to find the difference that you need to fill.
105-(85-10)= 10
not sure tho
