Ok. So let's first try to make an equation... (82+75+71+2x)/4 = 80

anonymous · Answer

After that we just figure out what x is..

it also says on a side not that assume that the maximum possible score on each test is 100. sorry I didnt write that with the q.

anonymous · Answer

It's okay... tbh, I really don't know where I got wrong on the equation! Sorry :(

vegan555 · Answer

no its ok, I figured it out, I took 400% total because there is 4 tests and subtracted the three tests scores from 400 and divided by two to give me 86%.
