But don't we have order by earnings/day first?

12 12 12 12 12 12 12 20 20 20 20 23 23 23 24 24 24 24 24 24

so avg of days 10 and 11 = 20.

so from explanation I should do:
48 (2) 70 (3) 80 (4) 84 (7) 96 (4). so 2 + 3 + 4 = 9, so 10 and 11 fall inside the $84?

"The number of days that the student earned that amount",not the "total amount"
which would mean 48, 48, ....
