If a company sells 300 watches at $48.00 per watch and has variable cost of $ 18.00 per watch and fixed cost of $ 4,000.00. What is the projected profit?
I need to know how to get the answer for the two (?) marks.

Profit = Contribution Margin - Fixed Costs

= ? ( $48 - $18 ) - $ 4,000.00
= ? ( $30 ) - $ 4,000.00
= $9,000 - $4,000
= $5,000

Your answer is correct.

Simply:

(300 units sold * ($48 - 18)) - $4,000 = $5,000 gross profit.
