Question: Jimmy decides to make sandwiches for a picnic.  He makes 8 sandwiches in total, using two slices of bread each.  How many packs of bread does he need to buy to make these sandwiches, assuming he starts with no bread and each pack has 4 slices of bread in it? Is final answer 3?
Answer: First, we need to determine how many slices of bread Jimmy will use to make the sandwiches. We determine this by performing 8*2=<<8*2=16>>16 slices of bread needed.
We then divide the number of slices needed by the number of slices per bread pack, performing 16/4=<<16/4=4>>4 packs of bread needed.
