Final answer:
To find the list price of the tractor, we divided the purchase price of $25,800 by 0.86 (representing 86%, the remainder after a 14% discount). The list price was $30,000 before the trade discount was applied.
Step-by-step explanation:
The student's question pertains to finding the list price of a tractor given the purchase price after a trade discount has been applied. In this scenario, the tractor was bought for $25,800 after a 14% discount was deducted from the list price. To calculate the original list price, one would divide the purchase price by the percentage that represents the final amount after the discount (which is 100% - 14% = 86%).
Calculation:
Therefore, the list price of the tractor was $30,000 before the trade discount.
