An electrician charges $75 for the first hour of labor and $60 for each additional hour of labor. A customer calculates that the electrician charges $225 for a total of 3.5 hours of labor. Is the customer correct?

Respuesta :

yes the customer is right. they will have to pay $225 for 3.5 hours of labor
NOOOO if you write an equation: 225= 75 + 60 x 3.5, you actually get 285. the actaul answer is 225 dollars for 2.5 hours!
