Question: Roger's age is 5 more than twice Jill's age. In 15 years, their age difference will be 30 years less than Finley's age. If Jill is 20 years old now, how old is Finley?
Answer: Twice Jill's age is 2 * 20 = 40. If Roger's age is 5 more than twice Jill's age, he is 5 + 40 = 45 years old. In 15 years, Jill will be 20 + 15 = 35 years old. Roger's age will be 45 + 15 = 60 years old in 15 years. The age difference between Roger and Jill in fifteen years will be 60 - 35 = 25 years. In 15 years, the age difference between Roger and Jill will be 30 years less than Finley's age, meaning in fifteen years Finley will be 30 + 25 = 55 years old. Currently, Finley is 55 - 15 = 40 years old. The answer is 40.
[Question]Zoe goes to the store to buy soda and pizza for herself and her 5 family members. Each bottle of soda costs half a dollar and each slice of pizza costs $1. Before she leaves her house she takes just enough money to pay for her purchase. How much money did Zoe take?
[Answer]Zoe is going to buy pizza and soda for 5 people + 1 person = 6 people. For 6 sodas, Zoe will pay 6 sodas * $0.5 / soda = $3. For 6 slices of pizza, she will pay 6 slices * $1 / slice = $6. Adding the price of the soda and pizza, Zoe paid $3 + $6 = $9. The answer is 9.

[Question]Charlie owns one flute, two horns, and a harp. Carli owns twice as many flutes as Charlie, half as many horns as Charlie, but no harps. What is the combined total number of musical instruments owned by Charlie and Carli?
[Answer]
Charlie owns one flute, two horns, and a harp for a total of 1 + 2 + 1 = 4 instruments. Twice as many flutes as Charlie is 2 * 1 = 2 flutes,. Half as many horns as Charlie is 2 / 2 = 1 horn. Thus, Carli owns 2 + 1 = 3 instruments. Therefore, the combined total number of musical instruments owned by Charlie and Carli is 4 + 3 = 7 instruments. The answer is 7.
