Another Solving Inequalities

I used to be a consultant for Scentsy Wickless Candles. Instad of just taking orders over the computer or doing parties for others I would rent a booth at fairs, or flea markets. Column A would be the items I would need in order to do these events and Column B would be the items that I would sell.

Column A

Rent a booth or table: $30 Variable=R

Gas to get back and forth from the event: $15 Variable=G

Order Forms: $10 Variable=F

Decorations to make table stand out: $15 Variable=D

Reciepts: $10 Variable= A

Column B:

Large Warmer: $40 Variable=L

Medium Warmer: $30 Variable=M

Plug in Warmer: $25 Variable=P

Scentsy bars (wax): $5/ea Variable=B

Room Sprays: $8 Variable= S

Total of Set A= $80

Total of Set B= $108

The prices for Set B are each...So $40 for each large warmer, and so on. I hope I did this right.
