Lizzy: Charlotte is a dog walker and is creating a schedule for all of her clients this week. Each dog is walked separately. On Monday, she needs to walk 4 poodles and 2 Chihuahuas. On Tuesday, she walks the same amount of Chihuahuas but isn't sure how many poodles she should walk. On Wednesday, she walks 4 Labradors. It takes 2 hours to walk a poodle, 1 hour to walk a Chihuahua, and 3 hours to walk a Labrador. If she has time for a total of 32 hours spent in dog-walking this week, how many poodles can Charlotte walk on Tuesday?.
Me: Hmmm, let me think. I think this is the detailed solution:
On Monday, she spends 4 poodles * 2 hours = 8 hours walking poodles. On Monday, she spends 2 Chihuahuas * 1 hour = 2 hours walking Chihuahuas. On Tuesday, she spends 2 Chihuahuas * 1 hour = 2 hours walking Chihuahuas. On Wednesday, she spends 4 Labradors * 3 hours = 12 hours walking Labradors. Over the week, this is a total of 8 + 2 + 2 + 12 = 24 hours spent dog - walking. This means she still has 32 maximum hours – 24 used hours = 8 hours available for dog - walking. Therefore, she can walk 8 hours / 2 hours per poodle = 4 poodles on Tuesday. Final answer: 4.
