Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $40 to come to his house and $60 for every hour they work. If the plumber charges Jerald a total of $190, how many hours did the plumber work? Write and solve an equation to determine the number of hours worked by the plumber. 60x + 40 = 190; x = 2.5 hours 60x − 40 = 190; x = 3.8 hours 40x + 60 = 190; x = 3.25 hours 40x − 60 = 190; x = 6.25 hours
