Narchie sells a single product for $60. Variable costs are 60% of the selling price, and the company has fixed costs that amount to $480,000. Current sales total 17,000 units. If Narchie breaks even by selling 20000 units, after the break -even pointeach unit that Narchie sells will:

increase profit by some other amount.

increase profit by $24.

increase profit by $60.

decrease profit by $6.

increase profit by $36.

How do I go about solving this? Kindly provide a step by step solution. Thanks in advance.
