Tony's baby-sitting service charges $8.50 per job plus $6.75 per hour. what is the cost of a 7-hour baby-sitting job ?

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

The answer is $9.90 with rounding to the nearest tenth
