Question 876692: An electrician told Mrs. Aba that the labor required to repair the electrical problem cost $150. The bill included a base service call charge of $40 plus $25 per hour. Without solving, write an equation that could be solved to determine the number of hours the electrician worked. Indicate what the variables represent.
