Answer :
Given in the question:
a.) A coat is marked down 40% off.
b.) The original price was 115.00.
To be able to determine the price we will be using the equation below:
[tex]\text{ Discounted Price = (Original Price) x (}\frac{\text{ 100 - \% Discount}}{100})[/tex]We get,
[tex]\text{ Discounted Price = (Original Price) x (}\frac{\text{ 100 - \% Discount}}{100})[/tex][tex]\text{= (115.00) x (}\frac{\text{ 100 - 4}0}{100})[/tex][tex]\text{ = 115.00 x 0}.60[/tex][tex]\text{Discounted Price = }69.00[/tex]Therefore, the price of the coat will be 69.00.
