Question 325491
From the information that you provided, we are assumming that you desire a 20 percent profit based on the manufacturers selling price. Here goes: 

Each sewing machine carries an added cost of 200 dollars. 

The base price of each machine is 450 dollars + profit + overhead. 

20 percent of 450 is 90 dollars
450 + 90 dollars is 540 dollars

540 dollars + 200 dollars overhead results in a base price of 740 dollars for each machine!

Hope we could be of help. Should you require additional help in math, please check out our website (see our profile for the link)
