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? Give the rationale and then the answer.
Let's think step by step. 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.

There are 12 crates that each contain 150 oranges. There are 16 boxes that each hold 30 nectarines. How many pieces of fruit are in the crates and the boxes in total? Give the rationale and then the answer.
Let's think step by step. Oranges = 12 * 150 = 1800. Nectarines = 16 * 30 = 480. 1800 + 480 = 2280. There are 2280 pieces of fruit in total.. The answer is: 2280.

Jasmine and her older sister Alexa went to the store to buy shoes. Alexa's shoes are twice as big as Jasmine's shoes. If Jasmine's shoe size is 7, what's the combined shoe size for both of them? Give the rationale and then the answer.
Let's think step by step. If Alexa's shoes are twice those of Jasmine, then her shoe size is 7 * 2 = 14. The total shoe size is 14 + 7 = 21.. The answer is: 21.
