As calculating interest per day is a little trickier than calculating by simple years, additional practice is needed. Why all of the attention on interest? There is interest that needs to be paid (or earned) on almost everything in life. That’s just one of the reasons that math is and will always be an important part of your life and it will play many roles throughout as well. That is also what business math is all about. Teaching you everyday math and how it applies. This is math that you will use and the more you know about it and understand it, the better informed you will be to make some serious decisions in life such as what kind of a car should you get, what colleges can you afford to get into, getting married and the expenses involved in that. Then there is buying a house or going on a big vacation.
$695.00 at 5.2% for 632 days.
I = PRT
695 x 0.052 x 632/365
695 x 0.052 = 36.14
$36.14 per year
36.14 ÷ 365 (days) = 0.0990137 per diem
$0.0990137 x 632 (days) = $62.5767
I = $62.58
Answer (d) is the correct answer
