Step-by-step explanation:

Consider the provided information.

A used electronics store pays $50 for each cell phone, spends $15 refurbishing the phone, and sells the refurbished phone to a customer for $120.

Let x to represent the number of cell phones they sell.

Therefore the required expression is:

Company's earnings = $-50x-15x+120x$

Simplify the expression as shown.

$55x$

Hence, the required expression is $55x$ dollar

Part (B) What does the coefficient of the expression in part (a) represent?

The coefficient of the expression is the amount (in dollars) the company earns from each phone.
