To make 20 biscuits, the recipe requires:
- 150g butter
- 75g caster sugar
- 180g plain flour
- and 50g chocolate chips
We can use these amounts to calculate how much of each ingredient Jamie needs to make the maximum number of biscuits possible with the ingredients he has:
First, we need to figure out which ingredient will run out first. We can do this by dividing each amount Jamie has by what is needed for one batch (i.e., multiplying everything in the list above by two since one batch makes ten biscuits):
For butter:
800 / (150 * 2) = ~2.67 batches
For caster sugar:
700 / (75 * 2) = ~4.67 batches
For plain flour:
1000 / (180 * 2) = ~2.78 batches
For chocolate chips:
200 / (50 * 2) = ~1 batch
Since Jamie only has enough chocolate chips for one batch, that means he can only make as many biscuits as there are chocolate chips available, which is ten.
However, he could potentially make more if he had enough of all other ingredients. Based on our calculations above, it looks like his next limiting factor would be either plain flour or butter. If he had more of those ingredients relative to sugar and chocolate chips, then he could potentially make a larger number of biscuits.
So in summary,
Jamie can only bake up to **ten** cookies using all listed quantities because his supply runs out after making them
