A store purchased 20 coats that each cost an equal amount and then sold each of the 20 coats at an equal price. What was the store's gross profit on the 20 coats?

1) If the selling price per coat had been twice as much, the store's gross profit on the 20 coats would have benn $2400 2) If the selling price per coat had been$2 more, the store's gross profit on the 20 coats would have been \$440

huh?
what am i missing?
gross profit (GP) = revenue (SP) - cost of merchandise (CP)
S1 gives:
GP =2400 and SP = 2xCP
so GP = 2xCP - CP = 2400 = CP

I must be brain dead tonight!

BTW I started looking at this site a few weeks ago -- It is very cool and very helpful.
