1. Use the simple interest formula, I = Prt to find the unknown value. a . |=?, P=$800, r=10%, t=6 years b. 1=$50, P=$100, A=? C. 1=$567, A=$2300, P=? d. 1=$37.92, P=?, r=5%, t=8 months 2 . Calculate the rate per compounding period, i, for each of the following. a. 9% per annum, compounded monthly b. 6% per annum, compounded quarterly c. 4.3% per annum compounded daily 3. Calculate the total number of compounding periods, n, for each of the following. a. Compounded semi-annually for 8 years b. Compounded monthly for 6 years c. Compounded weekly for 2 years 4. Use the compound interest formula, A = P(1+i)", to find the unknown value. a. A=?, P=$1200, i=0.06, n=20 b. A=$8000, P=?, i=0.05/6, n=12 5 . Use the formula, A = P(1+i)", to determine the amount of interest earned if the principal is $1900 and the amount is $2250. 6. How much would an investment of $800 be worth in 100 days if it earns simple interest of 8.4% per annum? 7. An investment of $2200 earned interest at 9.2% per annum compounded quarterly. How much would the investment be worth in 6 years? 8. A car loan can be taken for 5 years. At an interest rate of 8.4% per annum compounded monthly, the total cost of the car loan would be $37993.41. What is the cost of the car if you pay cash for it today rather than take out the loan? 9. Karen made an investment of $2500 two years ago to go on a trip. She invested the money at 7.2% per annum compounded semi-annually. Her investment will mature in three years. Dwayne would also like to go on the trip. However, he hasn't started saving yet. How much must he invest today at 9.6% per annum compounded monthly to have the same amount as Karen will have three years from now
