Answer:
System.out.println("This house is $"+currentPrice + ". The change is $"+ (currentPrice - lastMonthsPrice) + " since last month.");
System.out.println("The estimated monthly mortgage is $"+ ((currentPrice * 0.051) / 12)+ ".");
Explanation:
The rest of the code can be seen above. After getting inputs for current and last month's prices, we arrange them according to the output.
To find out the change since last month, we subtract currentPrice from lastMonthsPrice.
To calculate the mortgage, we use given formula (currentPrice * 0.051) / 12.
Please be aware the string concatenation - arranging variables using + sign.
