1)

4 months @ 7 = 28 cartons

8 months @ 9 = 72 cartons

(assuming the year has 12 months instead of 11)

average apples sold per month is 100*66/12 = 550

2)

since the sum is 48, and no single reading is over 20, then the smallest must be at least 8.

3)

sum of numbers is 50*38 = 1900

new sum, less discarded values = 1800

new average is 1800/48 = 37.5
