We asked 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.

The answer to this question was that the basic order is not enough to get the bulk price and we need to order another two bags.

You can work this out two ways.

Method 1 : First fInd out how many bags you need to order to make a one tonne order

1 tonne of food is 1000kg

Each bag weighs 20kg

so to find out how many lots of 20kg (bags) make 1000kg we divide 1000 by 20

1000/20 = 100/2 = 50

So we need 50 bags to get the bulk price

Then to find out how many bags on the order we add them all together

1 bag aviary mix

20 bags layers pellets

8 bags of mixed corn

1 bag of rabbit pellets

3 bags of pot bellied pig pellets

1 bag guinea pig pellets

2 bags of beef nuts

5 bags of ewe nuts

5 bags of goat mix

+ 2 bags of sugar beet

———

= 48 bags total

We need to order 50 bags so that’s an extra 2 bags (50-48=2 or 48+2=50)

Method 2: First work out how much the base order weighs

Add up the total number of bags as above which gives 48 bags

Each bag weighs 20kg so that is 48x20kg for the whole order

48x20 =960 so Dean’s base order is 960kg

Work out how much more weight we need to order by taking away 960kg from 1000kg (1 tonne)

1000 - 960 = 40 kg

How many bags makes 40kg?

20 goes into 40 two times 40/20 =2 or 20+20=40

so 2 20kg bags are needed for the bulk order price
