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

the year? (Assume that Edna will make no payments or new purchases during
the year, and ignore any possible late payment fees.)
