Question: A printing press is printing brochures. The press prints 20 single-page spreads, and twice as many double-page spreads. For each 4 pages printed for the spreads, the press prints a block of 4 ads, each of which take up a quarter of a page. The brochures can be arranged in any order as long as they are made up of 5 pages each. How many brochures is the printing press creating?
Answer: There are a total of 20 single - page spreads * 2 = 40 double - page spreads. As these are made up of 2 pages each, there are 40 double - page spreads * 2 pages = 80 pages in the double - page spreads. In total, there are 20 single - pages + 80 double - pages = 100 pages in the spreads. A block of ads is printed every 4 pages, so there will be 100 pages / 4 pages / block = 25 blocks of ads. This is a total of 25 blocks * 4 ads = 100 ads. As each ad takes up a quarter of a page, this must create an additional 100 ads * 0.25 = 25 pages. Therefore, the press has printed 100 pages from the spreads + 25 pages of ads = 125 pages. Since brochures are made up of 5 pages each, this creates a total of 125 pages / 5 = 25 brochures. The answer is 25.
[Question]Tom cannot afford a normal doctor, so he goes to a discount clinic that is 70% cheaper. It takes two visits, though, instead of 1. A normal doctor charges $200 for a visit. How much money does he save?
[Answer]Each of Tom's visits was 200 * .7 = $140 cheaper. So he paid $200 - $140 = $60 per visit. That means he paid $60 * 2 = $120. So he saved $200 - $120 = $80. The answer is 80.
Q: Charlie owns one flute, two horns, and a harp. Carli owns twice as many flutes as Charlie, half as many horns as Charlie, but no harps. What is the combined total number of musical instruments owned by Charlie and Carli?
A: Charlie owns one flute, two horns, and a harp for a total of 1 + 2 + 1 = 4 instruments. Twice as many flutes as Charlie is 2 * 1 = 2 flutes,. Half as many horns as Charlie is 2 / 2 = 1 horn. Thus, Carli owns 2 + 1 = 3 instruments. Therefore, the combined total number of musical instruments owned by Charlie and Carli is 4 + 3 = 7 instruments. The answer is 7.
Question: Three cats sat on a fence, meowing at the moon. The first cat meowed 3 times per minute. The second cat meowed twice as frequently as the first cat. And the third cat meowed at one-third the frequency of the second cat. What is the combined total number of meows the three cats make in 5 minutes?
Answer: The second cat meowed twice as frequently as the three meows per minute from the first cat, for a total of 2 * 3 = 6 meows per minute. The third cat meowed at one - third the frequency of the second cat, for a total of 6 / 3 = 2 meows per minute. Thus, combined, the three cats meow 3 + 6 + 2 = 11 times per minute. In five minutes, the three cats meow 5 * 11 = 55 times. The answer is 55.

[Question]Milly and Floretta are having a water balloon fight in their garden. They use 3 packs of their own water balloons and also use 2 packs of a neighbor's water balloons. Each pack of water balloons contains 6 balloons. Milly and Floretta fill all of the balloons then split them evenly, but Milly takes an extra 7 balloons when Floretta isn't looking. How many water balloons is Floretta left with?
[Answer]
Milly and Floretta have a total of 3 packs of their own water balloons + 2 packs of the neighbor's water balloons = 5 packs of water balloons. So there is a total of 5 packs of water balloons * 6 balloons per pack of water balloons = 30 water balloons available. As they split them evenly, they each have 30 water balloons / 2 = 15 water balloons. After Milly steals some balloons, Floretta is left with 15 7 = 8 water balloons. The answer is 8.
