Explanation for Question 5 From the Math (No Calc) Section on the 2017 October Sat
Question five says the equation above gives the amount, 2 see in dollars an electrician charges for a job that takes eight hours. 3 Ms. Sanchez and Mr. Roland, each hired this electrician, 4 the electrician worked two hours longer on Ms. 5 Sanchez's job. Then on Mr. Rollins job, 6 how much more did the electrician charge Ms. 7 Sanchez than Mr. Rolon? So all we need to know here is 8 that every extra hour it takes is another $75 9 charged, which means that if the job took two extra hours, 10 all we would have to do is add 75 times two. 11 And if you do 75 times two, 12 you get $150. 13 So since Ms Sanchez's job took two extra hours, 14 we're adding 75 plus 75, 15 which is 150. So it should charge 150 more dollars. 16 And the answer is.
