First step, find the monthly payments.
Borrowed amount, P = 210000
Monthly interest, i = 0.045/12
Number of periods, n = 30*12=360
Monthly payment



[to the 1/100 of a cent]
2. Calculate interest accumulated over 60 months


3. Calculate value of payments



to the nearest cent
4. Calculate percentage of interest paid
A. as a fraction of future values
Percentage of interest
=52877.12/71445.50
=74.01%
As a fraction of total amounts paid
Percentage of interest
=52877.12/(60*1064.0392)
=52877.12/63842.35
=82.82%
<span>The product price and the average total cost determines the profit. If a company is charging a higher price than the per-unit cost, then they are earning a profit on that item. If they increase the price with everything else remaining constant, their profit increases. The opposite happens when they lower the price, all else held constant.</span>
