To find out how much interest will be paid on a $155,000 house if a monthly payment of $850 is made for 30 years, we can use the formula for the total interest paid on a fixed-rate mortgage loan:
Total Interest = (Monthly Payment x Number of Payments) - Loan Amount
where Monthly Payment is $850, Number of Payments is 30 years x 12 months/year = 360 months, and Loan Amount is $155,000.
Plugging in these values, we get:
Total Interest = ($850 x 360) - $155,000
Total Interest = $306,000 - $155,000
Total Interest = $151,000
Therefore, the total interest paid on the $155,000 house over 30 years with a monthly payment of $850 is $151,000.
