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.
