Question

A deposit of Po into a bank account has a doubling time of 50 years. No other deposits or withdrawals are made.

a. How much money is in the bank account after 50 years? 100 years? 150 years?

b. How many times does the amount of money double in t years? Use this to write a formula for P1, the amount of money in the account after t years.

***I'm confused on how to do this... Could you please explain this to me? Thank you :)

Answer 1

a) \(P_0, 2P_0,4P_0,8P_0\)

Answer 2

sorry i'm not sure what that means? :/

Answer 3

from yours: A deposit of Po into a bank account has a doubling time of 50 years
At the beginning, the amount of money is Po right?
after 50 years, it is double, it means at that time, the amount of money is 2Po

wait was that supposed to be latex? this is what shows up on my side :/

Answer 5

I don't know why, I cannot use draw box below, either.
