Mary is writing a story, and wants her 60 characters to be split according to their initials. Half of her characters have the initial A, and half of this amount have the initial C. Mary wants the rest of her characters to have the initials D and E, but she wants there to be twice as many characters with the initial D as there are characters with the initial E. How many of Mary's characters have the initial D?
Let's think: Half the characters have the initial A, which is a total of 60 / 2 = 30 characters. This means that 30 / 2 = 15 characters have the initial C. Mary wants the remaining 60 30 15 = 15 characters to have the initials D or E. For there to be twice as many characters with the initial D, the characters are divided into 2 + 1 = 3 parts. Dividing by this means there are 15 / 3 = 5 characters with the initial E. This leaves 15 5 = 10 characters with the initial D.. The answer is: 10.

A party store ordered 5 boxes of balloons. Each box contains 8 bags of balloons, and there are 12 balloons in each bag. How many balloons are there?
Let's think: The five boxes have a total of 5 x 8 = 40 bags of balloons. So, there are 40 x 12 = 480 balloons.. The answer is: 480.

Jeff spends three times as many hours on the weekend catching up with his Facebook pals as he does working. Monday through Friday, however, he spends four times as many hours working as he does catching up. If he spends 3 hours every day catching up, how many hours does he spend working in an entire week?
Let's think:
On the weekend, Jeff works 3 / 3 = 1 hour each day. On the weekdays, he spends 4 * 3 = 12 hours working each day. Thus, he spends 2 * 1 + 5 * 12 = 62 hours working each week.. The answer is: 62.
