Answer:
w * (1 + 0.17) or w + (w * 0.17)
Explanation:
Here are two expressions that represent the retail price of an item with an original cost of w dollars, assuming that the store marks up the price by 17%:
Retail price = w * (1 + 0.17)
This expression shows that the retail price is equal to the original cost multiplied by the markup percentage (0.17) plus 1. For example, if the original cost of the item is $100, the retail price would be $100 * (1 + 0.17) = $117.
Retail price = w + (w * 0.17)
This expression shows that the retail price is equal to the original cost plus the markup amount (which is equal to the original cost multiplied by the markup percentage). For example, if the original cost of the item is $100, the retail price would be $100 + ($100 * 0.17) = $117.
