need equation help - gain or loss at sales

[gmblng]

Here's the question - I cannot find nor understand the books equations to solve it.
Please help!

Each table is sold for $25; the fixed costs are $140,000 for 30,000 tables or less, variable costs are $15 per table.

What is the firm's gain or loss at sales of 8,000 tables?

Thanks for the help!

Cost/table=140000/8000+15
Income/table=25
Profit/table = I-C =
25-(140000/8000+15) =
-7.5
loss=8000*7.5=$60,000

BTW: Break even point is 14,000 tables.
