Peppa Roney works in a pizza parlor. Her job is to make the pizzas with the proper amount of toppings so that every slice has ex
actly the same amount of each topping. Their large pizza is always cut into 13 slices. She knows that one can of olives has 278 olives in the can, and one package of pre-cooked sausage has 141 pieces of sausage in it. A super large order was placed by Barry M. Nitrate. He wanted 138 sausage and olive pizzas. If every slice of pizza has 15 olives on it, how many packages of sausage must Peppa open to use?
