The wholesale club sells a large box of crackers with 12 reams of crackers for $9.89. your local store’s box of crackers has 4 reams for $4.29. how much do you save by buying the 12 reams from the wholesale club?

To start off take the number of reams of crackers and divide by the total cost of the box: 12/9.89=1.21 and 4/4.29=0.93 to find out how much you pay per ream.
Then what I did was 12x0.93=11.16 (to find out how much you'd be paying with the local price)
Finally subtract 11.16-9.89= 1.27.
So in total you'd save $1.27.
Hope this helps
