Question 996926
.
Raul works two hours daily after school, Monday through Friday. On Saturdays he works eight hours at two dollars more per hour than on <U>weekdays</U>. 

If he makes $142 per week how much does he make per hour on weekends.  &nbsp;&nbsp;&nbsp;&nbsp;(! I corrected here weekends on weekdays (underlined !). Otherwise it doesnt make sense). 
-------------------------------------------------------------------


Let &nbsp;x&nbsp; be what Raul makes per hour on weekdays.

Then he makes &nbsp;2*5*x = 10x &nbsp;in total on weekdays, &nbsp;Monday through Friday.


On Saturday he makes &nbsp;8*(x+2) &nbsp;dollars.


The equation is


10x + 8*(x+2) = 142.


The solution is &nbsp;&nbsp;x = {{{(142-16)/18}}} = 7 &nbsp;dollars per hour on weekdays.


Hence, &nbsp;Paul makes &nbsp;&nbsp;x+2 = 7+2 = 9 &nbsp;&nbsp;dollars per hour on weekends.
