Using the information above, you can create an equation for your problem.
8.50+6.75h=t
h=hour
t=total
We want to know how much for a seven hour job, so we can plug the seven into the h (hour) value.
8.50+6.75(7)=t
Now we solve for t.
8.50+47.25=t
55.75=t
This gives us our answer. It would cost $55.75 to have Tony babysit for seven hours
