Did you hear that? Let's have an ice cream shop! We can have lots of money!
Yeah, that's bad. Hope we can have one here soon.
We need to rent a shop first. I saw a shop on the street that needs to rent. That costs £300 per month.
That's good. We need to buy some ingredients to make ice cream. We also need to buy some chairs and tables.

Let's sell 1 cup of ice cream £2, I think that we'll have a good business.
I've rented the shop. We can start selling ice cream next month. How much did you pay for the ingredients?
I payed £200 on the ingredients. I made 10 cups of ice cream and it used £5. I payed £50 for buying tables and chairs.
This ice cream shop is so nice!
I've sold 400 cups this month.
In this ice cream business, the fixed cost is the money for renting the shop and the costs for the chairs and tables. So the total of fixed cost is £350. But £300 needs to pay every month.
Total cost is fixed cost plus variable cost. Our total variable cost is £200. So our total cost is £550.
The variable cost in this business is the cost that we used to make 1 cup of ice cream. So our variable cost is £0.5.
If our total revenue is less than our total cost, then we make a loss.
This month our revenue is £800.
Because profit/loss=total revenue-total cost, and this month our total revenue is £800 and total cost is £550, so we have£250 profit.
