Question: Jolene and Phil have four children, each with the same birthday. They gave birth to their first child exactly 15 years ago. They gave birth to their second child exactly one year after the birth of their first child. They gave birth to their third child on the fourth birthday of their second child. Two years after the birth of their third child, they gave birth to their fourth child. How old, in years, is their fourth child?
Answer: Their 1st child was born 15 years ago, and therefore is 15 years old. Their 2nd child was born 1 year after their 15 - year - old child, and therefore is 15 - 1 = 14 years old. Their 3rd child was born 4 years after their 14 - year - old child, and therefore is 14 - 4 = 10 years old. Their 4th child was born 2 years after their 10 - year - old child, and therefore is 10 - 2 = 8 years old. The answer is 8.

[Question]A store ordered 300 more than twice as many pens as it did pencils at $5 each. If the cost of a pencil was $4, and the store ordered 15 boxes, each having 80 pencils, calculate the total amount of money they paid for the stationery.
[Answer]If the store ordered 15 boxes, each having 80 pencils, they ordered 15 * 80 = 1200 pencils. If the cost of a pencil was $4, the store paid $4 * 1200 = $4800 for all the pencils. Twice as many pens as pencils that the store ordered are 2 * 1200 = 2400. If A store ordered 300 more than twice as many pens as it did pencils, it ordered 2400 + 300 = 2700 pencils. Since the cost of the pens was $5, the store paid 2700 * $5 = $13500 for the pens. The total amount of money they paid for the stationery is 13500 + 4800 = $18300. The answer is 18300.
