-At the end of t years, the amount of money A in a savings account earning simple interest from an initial investment of $\mathrm { P }$ dollars at monthly rate $\mathrm { r }$ is given by the formula $\mathrm { A } = \mathrm { P } + 12 \mathrm { Prt }$ . Write an equivalent equation by factoring the expression $\mathrm { P } + 12$ Prt.

A) $\mathrm { A } = \mathrm { P } ( 12 +$ Prt $)$
B) $\mathrm { A } = \mathrm { P } ( 12 + \mathrm { rt } )$
C) $A = P ( P + 12 r t )$
D) $\mathrm { A } = \mathrm { P } ( 1 + 12 \mathrm { rt } )$
