Answer:
If the original cost of a laptop is $199.99 and there is a 13% markup, the retail price of the laptop would be:
Retail price = original cost + (original cost * markup)
= 199.99 + (199.99 * 0.13)
= 199.99 + 25.99927
= $225.98927
Rounded to the nearest cent, the retail price of the laptop would be $225.99.
