Question 1048281: Solve algebraically. William is going to hire a snow plowing service. Elizabeth charges an annual fee of $80 plus $5 each time she plows. Jon charges an annual fee of $50 plus $10 each time he plows. How many times would the snow need to be plowed for the cost of both plans to be the same?

Let each time s/he plows x
50+10x = 80+5x subtract 50 and subtract 5x on both sides
5x = 30
x = 6 times
----------------------
Proof:
50+(10*6) = 80+(5*6)
50+60 = 80+30
110 = 110 Correct
