Credit card A has an APR of 12.5% and an annual fee of $48, while credit card B has an APR of 15.4% and no annual fee. All else being equal, which of these equations can be used to solve for the principal, [tex]P[/tex], the amount at which the cards offer the same deal over the course of a year? (Assume all interest is compounded monthly.)

A. [tex]P(1+\frac{0.125}{12})^{12} + 48 = P(1+\frac{0.154}{12})^{12}[/tex]
B. [tex]P(1+\frac{0.125}{12})^{12} + \frac{48}{12} = P(1+\frac{0.154}{12})^{12}[/tex]
C. [tex]P(1+\frac{0.125}{12})^{12} - \frac{48}{12} = P(1+\frac{0.154}{12})^{12}[/tex]
D. [tex]P(1+\frac{0.125}{12})^{12} - 48 = P(1+\frac{0.154}{12})^{12}[/tex]
