This could be treated as a uniform rates problem.
             pay rate    time      pay
OFFICE         12         y        12y
BABYSIT        10         x        10x
MAXIMUM                  40
MINIMUM                           400

Is this enough for you to decide what to do, or what system of symbolic statements to make and solve?
