extremely hard brain-teaser.

Soccer Seats

The Centerville Soccer Field has 2 sections of seats, with 20 rows in each section. Each section has the same number of seats. There are fewer seats in the first row (row A) than in the last row (row T). The number of seats increases from row A to row T according to a pattern. The table below shows the number of seats for rows G through O of one section. Seats for the coming event to raise money for a homeless shelter sell for $3 each. All expenses will be paid by the local bank.
Row--Number of Seats
G-- 72
H-- 75
I-- 78
J-- 83
K-- 86
L-- 89
M-- 94
N-- 97
O-- 100
If all the seats are sold, how much money will be raised?
