Answer:
You can always compare to cost together but the big thing to look for is that you could be spending less for more on a product or the other way around, spending more for less product. you always want to go with the product that you are spending less money to get more product out of it.
Step-by-step explanation:
for example, say you are buying a pack of pencils, there is a pack of
10 pencils for 5 dollars
and
50 pencils for 10 dollarsthan
you would want to buy the second pack of pencils because you are getting each pencil for 50 cents rather than 2 dollars for each pencil in the first pack.
