Assume you have a balance of $$1400$ on a card with an APR of $15\%,$ or $1\mathrm{.}25\%$ per month. You start making payments of $$200,$ but at the same time you charge an additional $$60$ per month to the credit card. Assume that interest for a given month is based on the balance for the previous month. The following table shows how you can calculate your monthly balance. Complete and extend the table to show the balance at the end of each month until the debt is payed off. How long dose it take to pay off the credit card debt $?$
