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? Give the rationale and then the answer.
Let's think step by step. 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.. The answer is: 4.

On Monday, Matt worked for 450 minutes in his office. On Tuesday, he worked half the number of minutes he worked on Monday. On Wednesday, he worked for 300 minutes. How many more minutes did he work on Wednesday than on Tuesday. Give the rationale and then the answer.
Let's think step by step. On Tuesday Matt worked 450 minutes / 2 = 225 minutes. On Wednesday Matt worked 300 minutes - 225 minutes = 75 minutes more.. The answer is: 75.

Anna baked 60 cupcakes. She gives away 4/5 of the cupcakes to her classmates. Of the remaining 1/5 of cupcakes, she eats 3 cupcakes. How many cupcakes does she have left? Give the rationale and then the answer.
Let's think step by step. After giving away 4 / 5 of the cupcakes, Anna has 60 / 5 = 12 cupcakes. After eating 3 cupcakes, Anna has 12 - 3 = 9 cupcakes.. The answer is: 9.
