Question

Trevor bakes 8 batches of biscuits, with 14 biscuits in each batch. He sets aside 4 biscuits from each batch for a bake sale and puts the rest in a jar. How many biscuits does Trevor put in the jar?

Answer 1

Check out the explanation.

Explanation:

Trevor starts out with `8` batches of biscuits, with `14` biscuits in each batch:

`8*14=112`

That means Trevor would have `112` biscuits in total. But, not so fast. The word problem then states that he sets aside `4` biscuits from each batch and puts the rest in a jar. Now let's turn that into an expression:

`8*(14-4)`

Trevor would still have `8` batches of biscuits, but instead of there being `14` biscuits in each, there would be `10`. Why? Remember, Trevor removed `4` biscuits from each batch. Now let's simplify our expression:

`8*(14-4)`

`8*10`

And finally we have our answer:

`8*10=80`

Trevor would put `80` biscuits in a jar.
