You have a friend who is an artist. she asked you for assistance in pricing her paintings for an upcoming show. she knows how much she wants to get for a painting, but she does not know how to calculate the selling price. she wants to have a price that includes sales tax (8.25%), credit card fee (2.75%), and show commission (15% after sales tax and credit card fee are subtracted). for example, she wants to net $200 from the sale of a painting, but does not know how to calculate the selling price. your answer is to create an excel spreadsheet that calculates the selling price for her. in addition, she wants the selling price rounded up to the nearest whole dollar. your spreadsheet needs to show the artist the amount of sales tax, the credit card fee, and the commission she must pay.
