You hope to buy your dream car five years from now. Today, that car costs $62,500. You expect the price to increase by an average of 2.9 percent per year. How much will your dream car cost by the time you are ready to buy it? A. $69,023.16 B. $72,103.59 C. $73,340.00 D. $66,818.02 E. $68,666.67
FV= PV (1 + r)^t FV= 62500 (1 + .029) ^5 = 72103.59 Answer: B. $72,103.59
On your tenth (10th) birthday, you received $300 which you invested at 4.5 percent interest, compounded annually. Your investment is now worth $756. How old are you today? A. Age 30 B. Age 20 C. Age 31 D. Age 23 E. Age 21
FV=PV*(1+r)^t FV= $756 PV=amount received on tenth birthday=$300 r=interest rate on investment=4.5% N=number of years between tenth birthday and today=unknown $756=$300*(1+4.5%)^t $756/$300=(1.045)^t 2.52=(1.045)^t take log of both sides ln(2.52)=t ln(1.045) t=ln(2.52)/ln(1.045) t=21 Age today=N+10 years Age today=21+10 Age today=31 years Answer: C. 31 years old
You want to have $30,000 saved 5 years from now to buy a house. How much less do you have to deposit today to reach this goal if you can earn 3.5 percent rather than 2.5 percent on your savings? Today's deposit is the only deposit you will make to this savings account. A. $1,219.02 B. $891.18 C. $945.11 D. $1,256.43 E. $1,124.60
If the deposit made today earns 2.50% on the savings FV = PV (1+r)^t $30,000 = PV / (1 + 0.025)^5 PV = $30,000 x 1/ (1+ 0.025)^5 PV = $26,515.63 If the deposit made today earns 3.50% on the savings FV = PV (1+r)^t $30,000 = PV (1+0.035)^5 PV = $30,000 x 1/ (1+0.035)^5 PV = $25,259.20 So, the amount less to be deposited today to reach this goal = $26,515.63 - $25,259.20 = $1,256.43
You need $50,000 in 10 years. If you can earn 6% interest, how much do you need to invest today? A. $27,919.74 B. $27,939.74 C. $27,929.74 D. $27,959.74 E. $27,949.74
PV=FV *(1/(1+r)^t PV= 50,000 *(1/(1+.06)^10 Answer: A. $27,919.74
Which one of the following will produce the lowest present value interest factor? A. 6 percent interest for 8 years B. 6 percent interest for 10 years C. 6 percent interest for 5 years D. 8 percent interest for 10 years E. 8 percent interest for 5 years
Present value = future value X (1/(1+interest rate)^time) The present value interest factor is (1/(1+interest rate)^time) 1/((1+8)^10) = .4632 Answer: D. 8 percent interest for 10 years
Assume the total cost of a college education will be $245,000 when your child enters college in 15 years. You presently have $108,000 to invest for this purpose.
