Hey there!!
... Total cost = $= Down payment + Closing cost + monthly payment
First let's solve for down payment.
... <em>We know the down payment is 15% </em>
... 15% = 15 / 100 = 0.15
What is 0.15 of $250,000 ?
... 0.15 × 250000
... $37500
Now, let's solve for the closing cost.
... The closing cost is 3%
... 3% = 3 / 100 = 0.03
What is 0.03 of 250000 ?
... 0.03 × 250000
... $7500
Monthly payment is $282,089.89
Hence,
Total cost of the house = $37500 + $7500 + $282,089.89
... 45000 + 282089.89
... 327089.89 <em>Is the total cost. </em>
Hope my answer helps!!
