Eggy maths

In the news story you read that farmers can get 90p for a dozen organic eggs, 70p for free range and 35p for cage eggs. With this in mind, answer the following questions:

1. How much money could somebody make if they sold 240 dozen cage eggs as free range eggs?

2. How much would they make if they sold the same number of battery farm eggs as organic eggs?

3. How many dozen eggs would 9840 eggs work out as? You can use a calculator to answer this question but you'll need to work out the sum first!

4. 30m eggs are eaten in the UK every day. There are around 60 million people in the UK. If everyone at the same number of eggs, how many eggs would each person have to eat every WEEK to eat all the eggs up?


What do you think of the news story? Would you be furious if the free range eggs you bought ended up to be battery farmed eggs? Let us know at Have your say or send longer articles to Be a reporter.
