James bought a gallon of milk for $3, a bunch of bananas for $2, and paid 20% sales tax. How much money did James spend?
Let's think: First add up James' purchases that is $3 + $2 = $5. So, the amount of sales tax is $5 * .2 = $1. Hence, James spent a total of $5 + $1 = $6.. The answer is: 6.

Mobius is the fastest mule in Italy. She can run at a top speed of 13 miles per hour when she is without any load to carry, and she can travel at 11 miles per hour as her top speed when she carries a typical load. If she travels the 143 miles from Florence, Italy to Rome, Italy at top speed while carrying a typical load, then returns to Florence at her usual top speed without carrying a load, how long, in hours, will the trip take if she takes two 30-minute rest stops during each half of the trip?
Let's think: 30 minutes is 30 / 60 = 0.5 hours. Two 30 - minute rest stops take 0.5 * 2 - 1 hour. If she takes two rest stops per each half of the journey, then she takes 2 * 1 = 2 hours in rest time. With a load, at her top speed, she can travel 143 miles in 143 / 11 = 13 hours. Without a load, at her top speed, she can travel 143 miles in 143 / 13 = 11 hours. Thus, the round trip will take 13 + 11 + 2 = 26 hours.. The answer is: 26.

Miss Adamson has four classes with 20 students each. She makes a study guide for her class and uses 5 sheets of paper per student. How many sheets of paper will she use for all of her students?
Let's think: Miss Adamson has a total of 4 x 20 = 80 students. Thus, she will use 80 x 5 = 400 sheets of paper for all of her students.. The answer is: 400.

Mariel is a dog walker. While walking her pack of dogs, she gets tangled up in the leashes of another dog walker and their 3 dogs. There are 36 legs tangled up in leashes. How many dogs is Mariel walking?
Let's think:
There are 2 dog walkers and they each have 2 legs so that's 2 * 2 = 4 legs. The other dog walker is walking 3 dogs that each have 4 legs so that's 3 * 4 = 12 legs. The dog walkers have 4 legs and the other dogs have 12 legs for a total of 4 + 12 = 16 legs. There are 36 legs total and 16 belong to the dog walkers and 3 dogs so that leaves 36 - 16 = 20 legs. Dogs have 4 legs and there are 20 legs so Mariel is walking 20 / 4 = 5 dogs.. The answer is: 5.
