What is hsa?
She has a total of 314 points now.
After the fifth test, the total points possible is 500.
0.8 * 500 = 400
400 - 314 = 86
She'll need an 86% to get a mean score of 80.
Stephanie scored 88, 70, 84, and 72 on her first four science tests. What score does Stephanie need on her fifth science test to receive a mean score of 80?

high school assessment and thank you
how did you get 500 possible points?
and where did you get 0.8?
Mean = ∑x/n
80 = (88+70+84+72+x)/5 = ?
80 = (88+70+84+72+x)/5 = ?
=86 ok thank you i get it know
