Question

Directions:
For this project, you will visit an online marketplace website and choose three different products that you might want. For each product, you should provide a description of the item and the price that is stated on the website. Do not round to the nearest dollar. You will then calculate the cost of each item (including the sales tax rate for the state where you live) given three different circumstances. Be sure to use a different item for each calculation.

•Item 1: price of the item with sales tax (no other discount or markup)

•Item 2: price of the item after a 20% discount was applied, plus sales tax

•Item 3: price of the item after a 10% increase in price, plus sales tax
