Respuesta :
To get an average of 70 on his test Paul needs to score at least 66 on his third test
first you take 63 and 81 add them together you get 144 then divide by 2 because you have two numbers then you get 72.which means he got a 66% on his last test here is the work:
63+81+66=210
210 divided by 3=
70%
hope this helps
