An plumber charges $40 for each hour he works plus a $90 service charge. The total charge for a recent job was $330. Which equation could be used to determine the number of hours, h, that the plumber worked on the job? How many hours did he work?

• 330h + 40 = 90; 2 hours

• 40h + 90 = 330; 6 hours

• 40h + 330 = 90; 12 hours

• 90h + 40 = 330; 5 hours
