A website-hosting service charges businesses a one-time setup fee of $350 plus (d) dollars for each month. If a business owner paid $1,010 for the first 12 months, including the setup fee, choose the correct equation and solve it.
Value of D is 55 us dollars
So first you would figure out 1010-350 to find out the cost just for those 12 months without to set up fee.
Then you would divide 12 by y 660 to see how much is the additional cost per month.
