Solve the Problem $y = 2.62 x + 0.22$ $y = 5.71 x + 0.22$

Solve the problem.
-A company's expenses included many factors. In 2012, travel costs were 2.62% of the expense budget, increasing by 0.22% of the total expense budget per year. In 2012, office supplies were 5.71% of the expense budget, increasing by 0.05% of the total expense budget per year. Write a system of equations with two functions. Write one function that models the cost of travel as a percentage of the total expense budget x years after 2012, and another function that models the cost of office supplies as a percentage of the total expense budget x years after 2012.

A) $y = 2.62 x + 0.22$
$y = 5.71 x + 0.22$
B) $y = - 0.22 x + 2.62$
$y = - 0.05 x + 5.71$
C) $y = 0.22 x$
$y = 0.05 x$
D) $y = 0.22 x + 2.62$
$y = 0.05 x + 5.71$
