a) Find the following values using the equations. i) An initial RM600 compounded annually for 1 year at 6% ii) The present value of RM600 due in 1 year at a discount rate of 6% and compounded semiannually.

b) Suppose someone made this statement: Sales doubled in 5 years. This represents a growth of 100% in 5 years; so dividing 100% by 5, we find the growth rate to be 20% per year. Justify whether the statement is correct.

c) Estimate the interest rates earned on each of the following: i) You borrow RM720 and promise to pay back RM792 at the end of 1 year. ii) You lend RM720 and the borrower promises to pay you RM792 at the end of 1 year.

d) Find the future values of these ordinary annuity and annuity due RM500 per year for 8 years at 14%. Hint: Compounding occurs once a year.

e) Compute the present value of a RM600 perpetuity if the interest rate is 5%. If interest rates doubled to 10%, calculate its present value.
