Can someone check these inequality word problems to see if I did them right? Correct me if I'm wrong!

Write a linear inequality using word problems.
1. While at a bakery mitch decides to purchase some cupcakes and brownies to share with his friends. He can spend up to $25 and the bakery charges $2 for a cupcake and $1 for a brownie. I got 1x+2y<-25

2. A scouting troop from Greenpoint is organizing a crab feed to raise money for camp. They need to make at least $1,130 to cover the costs of the camp. Tickets for the crab dinner sell for $32 a piece. Those people who don't like crab can purchase the vegetarian ticket for $18 each. I got 18x+32y>-1,130

why the negative?

If you add up the money spent, it cannot exceed $25, so

x+2y <= 25

same for the other one. No negative amount needed if you add up the amounts received.
