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?
2 answers:
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!

therefore each side of this square room is about 10.95 feet.
Is this simultaneous equations?
if yes then the first step is
make one of the unknown as the subject
the answer would be D.
