Answer to Question #176109 in C++ for meng

Question

using if ___ else statement and switch case statement for each problem.

-Question 1      

The Last Stop Boutique is having a five-day sale. Each day, starting on Monday, the price will drop 10% of the previous day’s price. For example, if the original price of a product is $20.00, the sale on Monday would be $18.00 (10% less than the original price).

 

On Tuesday the sale price would be $16.20 (10% less than Monday)

On Wednesday - $14.58.

On Thursday - $13.12.

On Friday - $11.81.

Develop a solution that will calculate the price of an item for each of the five days, given the original price. Test the solution for an item costing $10.00.         

 

-Question 2

Make changes in the solution to problem 1 to SET the price at wholesale when the sale price drops below the wholesale price. Test the solution with the following prices:

 

Retail price: $20.00 & $25.00

Wholesale price: $10.00 & $20.00
