Final answer:
The buying price of the car was approximately $15,803.57, which is calculated by dividing the selling price of $17,700 by 1.12, to account for the 12% markup by Smith's Auto Market.
Step-by-step explanation:
Smith's Auto Market applies a markup, which we must reverse in order to determine the used car's buying price. In this scenario, the $17,700 that Smith's Auto Market charges for an automobile with a 12% markup is 112% of the purchase price.
Finding the initial price (P) prior to markup can be done using the following equation:
1.12 times P is $17,700.
We get the following when we divide both sides of the equation by 1.12:
P is equal to $17,700 / 1.12
After being rounded to two decimal places, P is $15,803.57.
This means that the car cost roughly $15,803.57 when it was purchased.
