I inferred 4% interest to be per annum.
Answer:
about 19 annual withdrawals
Explanation:
First, we note that Rachel plans to withdraw $5,000 at the end of each year from a starting balance is $63,296.48, excluding the 4% interests, the total withdrawals possible is
$63,296.48/$5,000 = 12.65 (in years)
Including the 4% interest;
4% x $63,296.48 = $2,531.85
To find the possible withdrawals we multiply by the initial period excluding interest rates
$2531.85 * 12 = $31,901/5,000= 6.38 (in years)
Total: 6.38 + 12.65 = 19.03 (in years)
