Suppose you start saving some money in an empty savings account that has an
annual interest rate of 1% compounded continuously. Suppose you put $3000 into the account
each year, deposited in small chunks very frequently throughout the year (so we assume the
money is put in “continuously." The total money added each year is $3000, though).
1.
, Write a differential equation modeling the amount of money A in the account
(a)
after t years. About how much money does the account have in 10 years?
-, Suppose after 10 years you stop putting money into the savings account
(b)
and start using it to buy coffee and a snack almost every day. Say you spend $10 of
it for 350 days of the year (so you can assume that $3500 is being removed per year
"continuously"). Approximately how long will the fund last?
