Carlos works Mon - Fri and sometimes Sat. Last week he worked 38 hours. Mon - Fri he earns $8.50, Sat $12.75, Last week he earned $340. How many hours did he work on Sat?

Make this chart:

             Hours    Dollars     Dollars     
             worked    per hr.    earned 
-------------------------------------------
Mon - Fri    38-x      8.50      8.50(36-x)
Saturday       x      12.75       12.75x
-------------------------------------------
Totals        38                   340

       

       

Solve that and get x = 4 hours worked Saturday.
