Question: Jordan decides to start an exercise program when he weighs 250 pounds. For the first 4 weeks, he loses 3 pounds a week. After that, he loses 2 pounds a week for 8 weeks. How much does Jordan now weigh?
Answer: He loses 3 pounds a week for 4 weeks for a total of 3 * 4 = 12 pounds. He loses 2 pounds a week for 8 weeks for a total of 2 * 8 = 16 pounds. All total he has lost 12 + 16 = 28 pounds. Jordan weighed 250 pounds and has lost 28 pounds so he now weighs 250 - 28 = 222 pounds. The answer is 222.

Question: Carly is a pet groomer. Today, her task was trimming the four nails on dogs’ paws. She trimmed 164 nails, but three of the dogs had only three legs. How many dogs did Carly work on?
Answer: Let N be the number of dogs with 4 legs Carly worked on. All the dogs with 4 legs had 4N paws. There were 3 * 3 = 9 paws on dogs with 3 legs. At 4 nails per paw, she trimmed 164 / 4 = 41 paws. She worked on 4N + 9 = 41 paws. Thus, she worked on 4N = 32 paws on dogs with 4 legs. She worked on N = 32 / 4 = 8 dogs with 4 legs. Thus, Carly worked on 8 + 3 = 11 dogs. The answer is 11.
