Well, if two burgers and one hotdog costs 4.82, and one burger and two hotdogs cost 3.70, you substract those to find the cost of one burger. Then you add that by two, and that's the cost of two burgers. Now you just need the cost of two hotdogs. Subtract the cost of two burgers and 4.82. Then divide that by two. That's answer!
