Question: Sarah uses 1 ounce of shampoo, and one half as much conditioner as shampoo daily. In two weeks, what is the total volume of shampoo and conditioner, in ounces, that Sarah will use?
Answer: Sarah uses 1 + 0.5 = 1.5 ounces of hair care products daily. Two weeks is 2 * 7 = 14 days. In 14 days, Sarah will use 14 * 1.5 = 21 ounces of hair care products. The answer is 21.

Question: In five years, Rehana will be three times as old as Phoebe. If Rehana is currently 25 years old, and Jacob, Rehana's brother, is 3/5 of Phoebe's current age, how old is Jacob now?
Answer: If Rehana is currently 25 years old, she will be 25 + 5 = 30 in five years. Rehana will be three times as old as Phoebe in five years, meaning Phoebe will be 30 / 3 = 10 years old in five years. Currently, Phoebe is 10 - 5 = 5 years old. 3 / 5 of Phoebe's age now is 3 / 5 * 5 = 3 years, which is Jacob's age. The answer is 3.

Question: Hank gave his wife, Delphine, a box of 24 chocolates for Valentine's Day. On the first day, Delphine ate 4 chocolates. On the second day, she ate 3 less than twice as many chocolates as she ate the first day. On the third day, she ate two less than the number she ate on the first day. And on the fourth day, she ate one less than she ate the previous day. On the fifth day, how many chocolates remained uneaten?
Answer: Twice as many chocolates as she ate the first day is 2 * 4 = 8 chocolates. And three less than twice as many chocolates as she ate the first day is 8 - 3 = 5 chocolates. Two less than the number she ate on the first day is 4 - 2 = 2 chocolates. One less than she ate the third day is 2 - 1 = 1 chocolate. By the end of the fourth day, 4 + 5 + 2 + 1 = 12 chocolates had been eaten. Thus, on the fifth day, 24 - 12 = 12 chocolates remained uneaten. The answer is 12.
