Harlamova29_29 [7]
Profit (P) is calculated by subtracting the total cost (C) from the total revenue (R). The calculations are shown below, 

       R = (1440 dozens) x (12 pieces / 1 dozen) x (25 cents/ piece) = $4320
                   C = (1440 dozens) x ($2.50 / dozen) = $3600
 
                          Profit = R - C = $4320 - $3600 = $720

Thus, the businessman's profit is $720.
