Answer: $10,607.92
Explanation:
The annual payment will be constant which means that it is an annuity.
The mortgage value is therefore the present value of the annuity.
Present value of annuity = Annuity * ( 1 - (1 + rate) ^ -number of years) / rate
100,000 = Annuity * ( 1 - (1 + 10%) ^ -30) / 10%
100,000 = Annuity * 9.4269144669883
Annuity = 100,000 / 9.4269144669883
= $10,607.92
