The electrician arrives at Laura’s house to fix her broken furnace. The electrician charges 90 dollars for the first hour and 60 dollars for each additional hour. If the total bill comes to 330 dollars how long will the electrician at Laura’s house?
Since the initial fee is $90, you will subtract $90 from $330, getting $240. Since every hour after 1 hour is $60, you would divide $240 by $60 getting 4 hours
