For Exercises 61-70, use the model A = P e r t or A = P ( 1 + r n ) r t , where A is the future value of P dollars invested at interest rate r compounded continuously or n times per year for t years. (See Example 11) If $4000 is put aside in a money market account with interest compounded continuously at 2.2%, find the time required for the account to earn $1000. Round to the nearest month.
