Edna transferred a balance of $1400 to a new credit card at the beginning of
the year. The card offered an introductory APR of 2.9% for the first 3 months
and a standard APR of 22.1% thereafter. If the card compounds interest
monthly, which of these expressions represents Edna's balance at the end of
the year? (Assume that Edna will make no payments or new purchases during
the year, and ignore any possible late payment fees.)
