Question 85875
the equation you seek is ... {{{v=p(1+r)^t}}}


where v is the value of the account ... p is the starting principal
r is the interest rate PER COMPOUNDING PERIOD ... t is the number of periods


b. quarterly means one fourth of 5% so r=.0125 ... 4 compoundings per year for 10 years so t=40 ... {{{v=10000(1+.0125)^40}}}


the others are done similarly
