Speaker: One of our favourites on the menu is our special chocolate brownie which we bake up in trays like this.

This is about roughly 30 portions.

The majority sell as a dessert but we need to keep some back, which we give away for free as petit fours with coffee.

Chef wants to make £150 profit from this one tray.

Now I know they sell the desserts downstairs for £7.

So the next thing I need to do is work out how many portions I have to sell to get the £150 profit.

Speaker: So the next thing I need to do is work out how many portions I need to sell in order to make Chef's £150 profit.

I do this by first looking up the cost price to make the brownie which my sheet says is £27.53 for 30 portions.

So I take £27.53 and I add on the £150 desired profit.

Which gives me a total of £177.53.

Now I know that they sell the desserts downstairs for £7 so all I have to do is divide £177.53 by 7 which is 25.36.

Now obviously I can't sell a third of a dessert so I need to round that up to 26 leaving me 4 portions to cut into petit fours to serve with coffee.

Speaker 1: So Daisy, how are you getting on?

Speaker 2: Well, Chef. I wanted to see how many portions I could keep back for petit fours whilst making your £150 profit.

First I worked out the cost price of all the brownies which was £27.53.

Then I added that on to your desired profit which was £150.

Then I divided that number by £7 because that's what we sell it for which gave me roughly 26 portions so these are the 26 portions that we're keeping for dessert so we have 4 left for petit fours.

Speaker 1: Very well done. Thank you.

Speaker 2: Thank you Chef.
