and part of the time he worked tutoring a high school student in mathematics.
He was paid $4.75 per hour in the restaurant and $15 per hour tutoring.
If he earned $126.50 total, how many hours did he work in the restaurant?
~~~~~~~~~~~~~~~

x hours worked in the restaurant and the rest, (18-x) hours worked tutoring.


Write the money equation


    4.75x + 15*(18-x) = 126.50  dollars, in total.


From the equation


    x = %28126.50+-+15%2A18%29%2F%284.75+-+15%29 = 14.


ANSWER.  14 hours working in the restaurant and the rest, 18-14 = 4 hours working tutoring.


CHECK.   14*4.75 + 4*15 = 126.50  dollars, in total.    ! Correct !
