Question

a coin collection worth $900 appreciates at a rate of 8% per year.

how much money will it be worth in 25 years?

Answer 1

A = Pe^rt where r= interest rate = 8% = .08, t = years =25, P=$900

A = 900e^(.08)(25)

= 900e^2

=$6,650.15 rounded off to nearest cent

but some may argue the formula is

A=P(1+r)^t

=900(1.08)^25 with annual compounding instead of continuous

=$6,163.63

but continous compounding makes more sense, if you think about it

at any rate the total value after 25 years is in that interval,no matter how you view the problem,

minimum 6163.63 to 6650.15
