Final answer:
The question involves calculating the extra payment amount x for a $36,000 loan with a nominal monthly interest rate of 9.2%, to be paid over 36 months with increasing payments. An exact answer can't be provided without additional information on interest compounding and payment structure.
Step-by-step explanation:
A student asked how much x should be if they have a loan of $36,000, which is paid off in 36 monthly payments with an increasing monthly payment scheme and a nominal monthly interest rate of 9.2%. In this loan's structure, payments of $900 are made at the end of each month for the first 12 months, $900+x for the second 12 months, and $900+2x for the last 12 months.
To calculate x, one must understand the concept of loan amortization and the effect of interest rates on payments over time, which are often determined using the present value of an annuity formula.
However, to answer this question accurately, further information such as the method of calculation for the nominal rate (compounded monthly, daily, etc.), as well as a specific formula corresponding to the payment structure, should be known. As this information is not provided, a precise answer cannot be given.
