Question

PLEASE PLEASE PLEASE TELL ME HELP HELP

Answer 1

Answer:

78%

Step-by-step explanation:

Ok to solve this we can write this as

80 = $\frac{73+82+85+83+x}{5}$

We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%

Your grade is the average of all of your scores hence the divided by 5

We next multiply both sides of the equation by 5 to get

400 = 72+82+85+83+x

400=  322+ x

78 = x

He must get a 78% minimum on his next test to get 80%

Hope that helps!
