Nolan and emily are both selling cookie dough for a fundraiser. Although Nolan has already sold four tubes emily hasn't sold any
yet. If Nolan start selling nine tubes per day and emily begin selling 10 to spray they will eventually sell the same amount of cookie dough. How many days will it take? How many tubs what you sell?
The equation for this is a^2+b^2=c^2 so your equation would be 7^2+20^2=X So you square the 7 and the 20 then take the square root of X and you get X=21.19 :)
