Answer:
To calculate the markdown amount, we can multiply the original cost ($87.50) by the markdown percentage (45%):
87.50 * 45% = $39.38
The markdown amount is $39.38.
The retail price is the original cost minus the markdown amount. Therefore, the retail price is:
87.50 - 39.38 = $48.12
Therefore, the markdown amount is $39.38 and the retail price is $48.12.
