[Question]Anna spent 1/4 of her money, and now she has $24 left. How much did she have originally?
[Answer]Let X be the amount Anna had originally. She spent X * 1 / 4 and has X - X * 1 / 4 = $24 left. Combining like terms, we get X * 3 / 4 = $24. Dividing both sides by 3 / 4, we get X = $32. The answer is 32.

[Question]Elvis is releasing a new album with 10 songs, but he doesn't want to waste too much time on writing. He spends 5 hours in the studio, where he writes, records, and edits his songs. Each song takes 12 minutes to record, then it takes 30 minutes to edit all of his songs. How many minutes did it take Elvis to write each song, if each song took the same amount of time to write?
[Answer]5 hours in the studio is the same as 5 * 60 = 300 minutes. To record all of his songs, Elvis takes 12 * 10 = 120 minutes. After editing and recording 300 120 30 = 150 minutes are left to write all of his songs. Songwriting therefore took 150 / 10 = 15 minutes per song. The answer is 15.

[Question]Dorothy, Julia, and Robert go to the store to buy school supplies. Dorothy buys half as many pens as Julia. Julia buys three times as many pens as Robert. Robert buys 4 pens. If one pen costs $1.50, how much money did the three friends spend in total on pens?
[Answer]
Julia buys 4 * 3 = 12 pens. Dorothy buys 12 / 2 = 6 pens. The total number of pens purchased is 4 + 12 + 6 = 22 pens. The total cost of the pens is 22 * $1.50 = $33. The answer is 33.
