Final answer:
a) The selling price of the house is $505,800. b) The estimate of the selling price is $558,000. c) The value of the house increased by $55,800 over three years.
Step-by-step explanation:
a) To find the selling price of the house, we need to calculate 124% of the purchase price.
Selling price = Purchase price + (124% of the Purchase price)
Selling price = $450,000 + (0.124 * $450,000)
Selling price = $450,000 + $55,800
Selling price = $505,800
Therefore, the selling price of the house is $505,800.
b) To estimate and check our answer, we can use the method of multiplying the purchase price by 1.24 (representing a 24% increase) to get an estimate of the selling price.
Estimate = Purchase price * 1.24
Estimate = $450,000 * 1.24
Estimate = $558,000
Since the estimate is close to our actual answer of $505,800, we can be confident in the accuracy of our calculations.
c) The value of the house increased by the selling price minus the purchase price.
Value increase = Selling price - Purchase price
Value increase = $505,800 - $450,000
Value increase = $55,800
Therefore, the value of the house increased by $55,800 over the three years.
