Niko is looking at two different options for a new cell phone plan. Plan A has a fee of $40 plus an additional fee of $0.04 per
minute. With this plan, the first 500 minutes are free. Plan B has a fee of $60 plus an additional fee of $0.02 per minute. With this plan, the first 800 minutes are free. After how many minutes would both options cost the same amount?
