Final answer:
The non-markup price of the shoes, which are sold for $193.21 with an 87% markup, is calculated to be roughly $103.32.
Step-by-step explanation:
The question asks for the calculation of the non-markup price of a pair of shoes that are sold with an 87% markup. To determine the non-markup price, we first need to recognize that the final price represents 187% of the non-markup price (100% + 87% markup). The calculation to determine the non-markup price is as follows:
Let x be the non-markup price. Then, x + 0.87x = $193.21.
Combining like terms, we get:
1.87x = $193.21
Divide both sides by 1.87:
x = $193.21 ÷ 1.87
x ≈ $103.32
Therefore, the non-markup price of the shoes is approximately $103.32.
