The program then calculates the item's retail price based on the following criteria: If the number of days it takes to sell the item is more than 7 days, the markup percentage is 100 percent. Ex.: the retail price of $5.00 item that sales in 9 days is $10.00. If the number of days it takes to sell the item is 7 days or less, the markup percentage is 70 percent. Use functions to do the following: - display description to user - calculate retail price - display output Use constant for threshold days (7 in this case) to sell the item. Include a loop that lets the user repeat the program until the user says she or he is done. 11.2 Write a program that converts feet and inches to centimeters.
