# Solve the following word problems, rounding dollars to the nearest cent and percents to the nearest tenth of a percent.A microwave oven cost The Appliance Warehouse $141.30 and was initially marked up by 55% based on selling price. In the next few months, the item was marked down 20%, marked up 15%, marked down 10%, and marked a final 10%. What was the final selling price of the microwave oven? To determine To calculate: The final Selling Price of the microwave oven, if cost is$141.30 and the markup based on selling price is 55%, where the item was marked down 20% and mark up 15%, marked down at 10% and again 10% marked down finally.

Explanation

Given Information:

The Cost is  $141.30 and the percent markup based on selling price is 55%. Formula used: The Selling Price can be calculated using the following equation: Selling Price=Cost100%%MSP or SP=C100%%MSP The Sale Price can be calculated using the following equation: Sale Price=Original Selling Price(100%Markdown%) or Sale=Original price(100%MD%) Another formula to calculate the Selling Price is: Selling Price=Sale Price(100%+%Markup) or SP=Sale price(100%+%M) Calculation: Consider the provided data, Cost$141.30, and percent markup based on selling price is 55%:

Assume, %MSP = 55% and  C =  $141.30 This markup and markdown series can be solved using the 5 steps as: Step 1: To calculate the Original Selling Price. The Original Selling Price is: SP=C100%%MSP Substitute for %MSP = 55% and C =$141.30 in SP=C100%%MSP:

SP=141.30100%55%=141.300.45=314

Therefore, the Original Selling Price of microwave oven, is $314. Step 2: To calculate the Sale Price, with markdown of 20%. The Sale Price is: Sale=Original price(100%MD%) Substitute for MD% = 20% and Orig =$107.78 in Sale=Original price(100%MD%):

Sale=314(100%20%)=314×0
