We simplify the problem by assigning terms such as below:
Let WC be equal to Warranty Cost.
Let PP be equal to the Purchase Price.
Since it is stated in the problem that the warranty cost is 35% of the purchase price, we can formulate an equation.
The equation is,
PP x 0.35 = WC
PP x 0.35 = $238
Then, we can solve for PP by dividing both sides by 0.35.
PP = $238/0.35
PP = $680
The answer is $680.
