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
