Problem - Contractor

PROBLEM SOLVING: The function $$C\left(x\right)=25x+50$$  represents the labor cost (in dollars) for Contractor A to build a deck, where x is the number of hours of labor. The table shows sample labor costs from its main competitor, Contractor B. The deck is estimated to take 8 hours of labor.
