L03 - Coupons

A supermarket awards coupons depending on how much a customer spends on groceries. For example, if you spend $50, you will get a coupon worth eight percent of that amount. The following table shows the percent used to calculate the coupon awarded for different amounts spent. Write a program that calculates and prints the value of the coupon a person can receive based on groceries purchased. Use printf to print formatted output. 
 Hint: Because the % symbol flags the beginning of a format specifier, if you want to actually print a % you'll need to enter it twice: %%
