Question

Duane’s scores on the first three math tests this quarter are 82, 74, and 96. Which is the lowest score he could get on the fourth test so that his average score will be at least 80 for the quarter?

Answer 1

Answer:

84

Step-by-step explanation:

(The sum of 82, 74, and 96 would be 252. And the count of numbers included in the question would be 3, and so you would divide the count from the sum as shown like Sum/Count. In this case it'd be 252/3, and that would equal 84.)

Average =  Sum/Count  

=   252/3  

=  84
