Milo received three 2s, four 3s, one 4, and one 5.
To calculate the average grade, we add up all the grades and divide by the number of grades.
The sum of the grades is 3(2) + 4(3) + 1(4) + 1(5) = 6 + 12 + 4 + 5 = 27.
The number of grades is 3 + 4 + 1 + 1 = 9.
So the average grade is 27 / 9 = 3.
Milo will receive $5 times the average grade, so he will receive 5 * 3 = $15.
