Answer:

you would have to score another 84%

First you want to find the sum of all the scores. add them all together and divide by the number of different scores. so this would be 400/5= 80

Answer:

84

Explanation:

there will be a total of five test scores so we know it will be divided by five.

to get an average score of 80 we can multiply 5*80 to get 400 all the other numbers must equal 400 added up so 400-(78+80+74+84)=x

400-316=x

84=x
