    The original cost is $199.00.
    The discount applied to that cost is 40%.
    To solve for the sales price, we can (a) apply the 40% to the 199.00 and subtract that discount amount from the 199.00, or (b) apply 60% to the 199.00 for the discount price. We can solve for this by simple multiplication (1), or dividing and then multiplying (2).
    (1a) Just multiplying, we would do 199.00 x .4, since .4 is the decimal value for 40%. This gives us $79.60 as the discount. 199.00 – 79.60 = 119.40. The final sales price is $119.40.
    (1b) Since we know percentages are ratios of a number n to 100 (or n/100), 40% discount means the sales price will be 60% of what the original was. 199.00 x .6 = 119.40. The final sales price is $119.40.
    (2) We can also solve by dividing and then multiplying. We would divide $199.00 by 100 since we are dealing with percentages, which are a ratio out of 100. 40% is the same as 40 parts out of 100 total parts, so if we first do 199.00 / 100, we can get the value of 1 part. Multiplying this value of 1 part by 40 gives us the 40 out of 100, which would be the discount amount– however, since the question is asking for the discounted sales price and not the discount amount itself, we can just multiply the value of 1 part by 60 to get the sales price.
    199.00 / 100 = 1.99 (value of 1 part)
    1.99 x 40 = 79.60 (discount amount)
    1.99 x 60 = 119.40 (discounted sales price)
    The final answer is $119.40.
