Question: Kendra has 4 packs of pens. Tony has 2 packs of pens. There are 3 pens in each pack. If Kendra and Tony decide to keep two pens each and give the remaining pens to their friends one pen per friend, how many friends will they give pens to? Think carefully first, then make a decision:
Kendra has 4 packs x 3 pens / pack = 12 pens. Tony has 2 packs x 3 pens / pack = 6 pens. In total Kendra and Tony have 12 pens + 6 pens = 18 pens. If they each keep 2 pens, they keep 2 x 2 = 4 pens. They will be able to give a pen to 18 pens - 4 pens = 14 of their friends. So the answer is 14.
