## Algebra 1: Common Core (15th Edition)

The shoe salesperson earns a weekly salary of 150 dollars, so you must add that to the salesperson's total salary which is represented by the equation. Along with the weekly salary, the salesperson also earns 2 dollars per pair of shoes sold; this is represented in the equation by $2n$. The variable, $n$, represents the number of pairs of shoes the salesperson sells. This is added onto his weekly salary giving the equation: $150+(2n)$.
