A company has the following sales, variable cost, and fixed cost. If sales increase by $10,000 then their profit increases/decreases by how much? Please use the solution below and where the numbers go, Im getting confused.

Sales $50,000

Variable Cost $9.800

Fixed Cost $30,000

Solution formula is below

1) Calculate the total cost of FC and VC for $50,000.

2) Calculate the increase in VC based on the % increase in Sales. VC/50000 * new sales

3) Add FC and VC based on new Sales $$

4) Compare total costs for both sales levels.
