Can you work out what we need to order to get the bulk order prices for our animal feed

Dean has worked out how much of each type of animal feed we need to order for the next month. Our feed supplier Marriages needs an order of at least 1 tonne for delivery to be able to offer us bulk feed prices and free delivery. Each bag weighs 20kg. Can you work out whether our order is enough and if not how many more bags will we need to add on to get the best prices.
