A store that sells skis buys them from a manufacturer at a wholesale price of $60. The store's markup rate is 50%. What price do
horsena [70]

Answer:

$90

Step-by-step explanation:

To solve this problem, you simply multiply $60 by 50%. Remember to change 50% into its decimal form (50% -> 0.5).

60 x 0.5 = 30

Now we add 30 to the original price of $60 to get our final answer.

$60 + 30 = $90
