Final answer:
The discounted price is determined by first increasing the original cost by 125% and then decreasing the new price by 50%. However, the calculated discounted price of $36.05 is not listed in the given options, suggesting a possible mistake in the question or the options.
Step-by-step explanation:
The discounted price of the set of dishes can be found by first calculating the marked-up price and then applying the 50% markdown. Here's how to do it:
- Calculate the marked-up price by multiplying the original cost of $57.68 by 125%, which is the same as multiplying by 1.25.
- The result gives you the new price after the markup.
- Apply the 50% markdown to this new price by multiplying it by 50%, which is the same as multiplying by 0.5.
- The result will give you the discounted price of the set of dishes.
Step-by-step calculation:
- $57.68 × 1.25 = $72.10 (marked-up price)
- $72.10 × 0.5 = $36.05 (discounted price)
So the discounted price after a 125% markup and a 50% markdown is $36.05, which is not one of the options provided. It appears there may be an error in the question or the options given.
