A chocolate box contains 200 bars. Thomas and his 4 friends take 1/4 of the bars and decide to divide them equally between them. One of Thomas's friends doesn't like chocolate bars very much and returns 5 of his bars to the box. Later, his sister Piper comes home and takes 5 fewer bars than those taken in total by Thomas and his friends so she can also share with her friends. What's the total number of bars left in the box?
Let's think: Thomas and his friends took 1 / 4 * 200 = 50 bars. The total number of bars left in the box was 200 - 50 = 150 bars. Since there are five of them sharing, each of them got 50 / 5 = 10 bars. After a friend returned 5 bars, there were 150 + 5 = 155 bars in the box. Piper took five fewer bars, that is 50 - 5 = 45 bars. The total remaining bars left in the box is 155 - 45 = 110 bars.. The answer is: 110.

A swarm of ants discovered a pile of sugar that spilled from a dropped bag. They begin to harvest it and carry it off to their anthill. Every hour, the ants remove 4 ounces of sugar. The bag of sugar held 24 ounces before it was dropped. After three hours, how many more hours will the ants need to harvest the remaining sugar?
Let's think: After 3 hours, the ants have removed 4 * 3 = 12 ounces of sugar. There are 24 - 12 = 12 ounces of sugar left. Thus, the ants need 12 / 4 = 3 more hours to harvest the remaining sugar.. The answer is: 3.

Lisa has 18 more dresses than Ana. If the number of their dresses combined is 48, how many dresses does Ana have?
Let's think: If Lisa's surplus of 18 dresses is taken away from the total, they will have 48 - 18 = 30 dresses in total. They would each have the same number of dresses from these 30 i.e. 30 / 2 = 15 dresses which is the number of dresses that Ana actually has.. The answer is: 15.

James made $4000 in January. The next month he made twice as much. In March, however, James made $2000 less than in February. How much has James made so far this year?
Let's think:
In February James made 4000 * 2 = 8000. In March James made 8000 - 2000 = 6000. In total for the year James has made 4000 + 8000 + 6000 = $18000.. The answer is: 18000.
