Kylie has 34 stamps in her collection. Her friend, Nelly, has 44 more stamps than Kylie. How many stamps do Kylie and Nelly have together? Give the rationale and then the answer.
Let's think step by step. Nelly has 34 + 44 = 78 stamps. Thus, Kylie and Nelly have 34 + 78 = 112 stamps.. The answer is: 112.

Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined. If each regular dinosaur weighs 800 pounds, find the combined weight of Barney and the five regular dinosaurs' weights? Give the rationale and then the answer.
Let's think step by step. If each regular dinosaur weighs 800 pounds, five regular dinosaurs weigh 5 * 800 = 4000 pounds. Since Barney the dinosaur weighs 1500 pounds more than five regular dinosaurs combined, he weighs 4000 + 1500 = 5500 pounds. The combined weight of Barney and the five regular dinosaurs' weights is 5500 + 4000 = 9500 pounds.. The answer is: 9500.

Katrina saw an ad that said if she signed up for her local recycling program, she could earn $5.00. When she signed up, they told her for every friend that she referred, the friend would receive $5.00 and she would receive another $5.00 per friend. That day, she had 5 friends sign up and another 7 friends by the end of the week. How much money in total did she and her friends make? Give the rationale and then the answer.

Let's think step by step. She signed up 5 friends, then an additional 7 for a total of 5 + 7 = 12 friends. Each friend received $5 so 12 * 5 = $60.00. And she received $5 for each friend so 12 * 5 = $60.00. Her initial reward was $5 and her friends made $60 for signing up and she received $60 when they signed up for a total of 5 + 60 + 60 = $125.00.. The answer is: 125.
