If you bought 25 shares of mtm stock at 221/4 per share and sold the stock for 333/4 per share, how much profit did you make?
a. $843.75
b. $556.25
c. $277.00
d. $287.50

I am assuming that you mean

22, which is 22.25
and
11, which is 33.75

so each share gives you a profit of 33.75-22.25=11.5
 
and you bought and sold 25 of them, so your profit is 21.5*25=287.50, the last answer!
