Answer: $168,130
Explanation: selling price = $197,800
Percentage profit = 15%
Profit = 15/100 × 197,800
Profit = 0.15 × 197,800
Profit = $ 29,670
But profit = selling price - cost price.
Hence, cost price = selling price - profit
Cost price = 197, 800 - 29,670
Cost price = $168,130
Cost price is the price the seller paid for the house
