Problem assignment. Complete the program to compute discount rate based on purchase amount and customer status, according to the following table Eurchase Amount Discount Rate Less than 50 10% 159 208 25% 500 or more, less chan 1000 1000 or more Any customer who is a special customer, and is receiving a discount of 20% or more gets an additional 2% discount For example, a special customer who makes a S300 purchase receives a 1 5% discount. A special customer who makes a S700 purchase gets 20% plus the additional 2%, for a total discount of 22%. n your program first use if.else if. else method to calculate the discount based on purchase amount. Then follow that with a single if statement with a logical operator to assign the 2% extra, if valid. Additional information: Dealing with percentages is usually done with the fractional value ( 0.05 for 5%, for example) so that calculations can be easily done. Note how the provided code multiplies the fraction by 100 in the printf) to get a displayable percentage value
