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.
