Problem text:

Melvin recently inherited $70,000. He invested part of it in a savings account and bought a Certificate of Deposit (CD) with the remainder. He invested $20,000 more in the CD than in the savings account. Both the CD and the savings account pay simple interest, and the interest rate on the CD is 1.5% higher than that on the savings account. At the end of two years, Melvin has accumulated $7,650 in interest. What is the annual interest rate on the savings account?

I am clueless on how to set this problem up.

Here's some explaination:

For the first part, I basically just looked at what it said, then changed the future values. For example, in one part it said her home appreciated 0.04 times, so I multiplied 65000 * 1.04 to get the 2003 value of 67600. Also, The net worth was assets - liabilities.

For the second part, the simple interest is the amount of money * rate * years.

For the third part, ordinary interest is that based on a 360 day year, and exact interest is that based on a 365 day year. Ordinary time is time based on 30 days per month and exact time is, well, exact time.

For example, in the second part, March 5 to May 5 is exactly 31 days, so that's exact time. However, ordinarily, that's 2 months, so ordinary times says 60 days. To do the question, here are the formulas I used:

ordinary interest and time = 4225 * .08 * 60/360
exact interest and time = 4225 * .08 * 61/365
ordinary interest and exact time = 4225 * .08 * 61/360


For the last part I pretty much followed the example. For instance, if you got 60,000 in inheritance, you could invest it at 10% interest for one year and get 60000 * 1.1 = 66000. If you wanted, you could invest just 54545.45 * 1.1 and get 60000 to buy the house later.

I hope this helped.
