Step-by-step explanation: You and your dog combined weigh 134 lbs, and you weigh 105 lbs so you subtract 134 lbs - 105 lbs = 29 lbs. Your dog is 29 lbs.
If theres only two colors, red and blue and for every six people who prefer red, there are six people who prefer blue then divide 48 in half and he should order 24 red pens and 24 blue pens.
