Suppose a young graduate is depositing money into a bank account continuously at the rate of about $5, 000 per year, and the account earns interest of 4% annually (compounded continuously). To start with let's say they have $18,000 in the account. Assuming they don't make any withdrawals, how much money is in the account after six years?
In this case the change in money has two contributions:
A. Tax refunds
B. The savings that are added
C. The interest earned
D. Donations to charity
