A seller of guitars wants to make a monthly profit of $5,100 selling his guitars. His instruments sell for $700.00 each. His fixed costs are monthly rent and utilities/$1,210., $2,500./Wages and benefits to his employee, and other expenses of $481.00. He realizes that for every dollar of a sale, 0.75 goes to fixed costs and anything over and above that is profit. Calculate the amount of sales revenue needed to achieve the target profit of $5,100 per month.
