COP3014-Foundations of Computer Science Assignment #10 Objectives: 1. Implement a friend function of a class; 2. Overload the 60 then discount percentage is 14%; Note: Apply discount percentage after the net cost has been calculate discount = net_cost * (discount_percentage) /100: (drop / 100 if you converted the discount_percentage to a decimal) d. The tax on a purchase (order_tax) is calculated by the following formula: purchase_tax =(net_cost * tax_rate/100 (drop/100 if you converted the rate from a percentage) e. The total cost of a purchase (rounded to the nearest hundredth) is calculated by the following formula: total_cost = net_cost + purchase_tax - discount. Note: All tax and cost calculations should be rounded to the nearest hundredths. 9. Overload operator all formatting of output 4.
