Final answer:
The retail price of an item originally priced at $150 with a 22% markdown is $117. This is calculated by converting the markdown percentage to a decimal and multiplying it by the original price, then subtracting the result from the original price.
Step-by-step explanation:
To find the retail price after a markdown, you first determine the amount of the markdown by multiplying the original price by the markdown percentage. Here, the original price is $150, and the markdown is 22%. To find the markdown amount, convert the percentage to a decimal (0.22) and multiply by the original price:
$150 × 0.22 = $33
Subtract the markdown from the original price to find the retail price:
$150 – $33 = $117
So, the retail price after a 22% markdown on an item originally priced at $150 is $117.
