A coat is marked down 40% off the original price. If the
original price was S115.00, what is the sale price of the
coat before sales tax?

$69.00

Step-by-step explanation:

Hi there,

In order to solve this problem, I used this formula:

Dollar Markdown = (markdown %)(original price)

You will end up with Markdown = (0.4) (115).

(Be sure to convert the percentage to a decimal value. (ex. 40% = 0.4))

After multiplying, we find that 46 dollars is 40% of the original price.

For the final step, simply subtract the original price by the amount marked down to get $69.00.

Hope this was useful. Cheers.
