In 2012, a Certain Country Recovered 26% of Its Municipal $\mathrm { P } = 1.8 \mathrm { t } + 17$

In 2012, a certain country recovered 26% of its municipal solid wastes through recycling, up from 17% in 2007. Let P represent the percentage recycled and t the number of years since 2007. Find a linear equation for P as a
Function of t.

A) $\mathrm { P } = 1.8 \mathrm { t } + 17$
B) $P = 0.9 t - 17$
C) $P = - 1.8 t + 7$
D) $P = 1.8 t + 24$
