Ella is cooking a turkey and a ham for Thanksgiving. It takes 15 minutes per pound to cook a turkey and 23 minutes per pound to
cook a ham. Ella is able to cook the turkey and the ham in 5 hours and 18 minutes. If the turkey weighs twice as much as the ham, how much do the turkey and the ham weigh?
To do this you need to work backwards. if you note the number as 'n' you can put 7n = 5600 to find n you simply divide both sides by 7 getting n = 5600/7 n = 800
