You paid $78 for 6 1/2 hours of work. what is your rate of pay?

12 dollars per hour. because 12*6=72 and 12/2 is 6 so 72+6= 78

6.5h = 78 is our equation
Divide both sides by 6.5 to solve for how much you paid per hour.
6.5h / 6.5 = h
78 / 6.5 = 12
H = 12

Your answer is:

Your rate of pay is $12 per hour.

I hope this helps!
