1 quarter = 25 cents.

1 dime = 10 cents.

3 quarters = 3*25 = 75 cents.

10 cents = 1 dime.

75 cents = 75 / 10 dimes

= 7.5 dimes.

Therefore 3 quarters equal 7.5 dimes.

multiply both sides by a

a * a = 1/a * a

a^ 2 = 1

6 x 75 = 450

7 x 80 = 560

8 x 85 = 680

9 x 90 = 810

Total all students in class = 6 + 7 + 8 + 9 = 30 students

Total score of whole class:

450 + 560 + 680 + 810 = 2500

Average = 2500 /30 = 83.3 = 83 1/3

Answer is C) 83 1/3
