Answer: 15,657.65
This is correct assuming COMPOUND INTEREST.
Calculating it with SIMPLE INTEREST the answer would have been different.
You must indicate what type of interest.

3. Assume Sheryl Jenkins wants to accumulate $532.15 in two years. She currently has $465.09 to invest. What interest rate must she earn on her investment (that is, if she deposits $465.09 today) to have $532.15 exactly two years from today?

Answers: 1.15
This answer is incorrect.
With COMPOUND INTEREST $465.09 invested
At 1.15% per annum would give you $578.21.
And not $532.15.
So the rate must be lower than 1.15.
Try again.
With these type of questions you must indicate
What type of INTEREST you are using.

4. Your neighbor is asking you to invest in a venture that will double your money in 3 year(s). Compute the return the he is promising you?

Answers: 648.18
This answer is incorrect.
The question is asking for a rate of return.
This should be expressed in a percentage per annum.
Again you must indicate whether you mean
COMPOUND or SIMPLE interest.

LET US TEST YOUR ANSWER 11

5. You want to withdraw $39,616 from your account at the end of one year and $50,997 at the end of the second year. How much should you deposit in your account today so that you can make these withdrawals? Your account pays 7 percent p.a.

Answers: 53,307.29

53,307.29 @ 1.07 = 57,038.49

57,038.49 - 39,616.00 = 17,422.49

17,422.49 @ 1.07 = 18,642.06

This amount is insufficient to withdraw the
stated second amount.
CONCLUSION :- You answer is incorrect.
