Which of the following mathematical expressions computes the annual percentage rate (APR) for short-term financing?

APR = Percentage cost per period Number of borrowing (interest) periods in one year

APR = (1 + Percentage cost per period)^{Number of borrowing (interest) periods in one year} + 1.0

APR = (1 + Percentage cost per period)^{Number of borrowing (interest) periods in one year} 1.0

APR = (1 + Percentage cost per period) ^{Number of borrowing (interest) periods in one year}

APR = Percentage cost per period + 1
