Please review my math, i was not good at this subject

if you made a total of 22 bets each bet is for the underdog and the odds were +150. Each bet is for $10

Out of the 21 bets there are 12 bets that won, making a gross profit of $180.00. (12X15)

The remain 9 bets are losers, making this gross total -90

The profit would be $90.00


Is this correct?

First you said "you made a total of 22 bets each bet is for the underdog", now if you won 12 you would have won $ 180, now you would have had to lose 10 giving you a loss of $100, giving you a profit of $ 80
