[Question]If Joe spent 1/9 of his pocket money of $450 on chocolates and 2/5 on fruits, how much money does he have left?
[Answer]Joe spent 1 / 9 * $450 = $50 on chocolate. Joe spent 2 / 5 * $450 = $180 on fruits. Joe has $450 - $50 - $180 = $220 left. The answer is 220.
Q: A family went out to see a movie. The regular ticket costs $9 and the ticket for children is $2 less. They gave the cashier two $20 bills and they received a $1 change. How many children are there if there are 2 adults in the family?
A: They gave the cashier $20 x 2 = $40. Since a $1 change was returned, this means the tickets cost $40 - $1 = $39. Two adult tickets cost $9 x 2 = $18. So, $39 - $18 = $21 was spent for the children's tickets. Each child's ticket costs $9 - $2 = $7. Therefore, there are $21 / $7 = 3 children. The answer is 3.
Question: James buys a weight vest for $250. He then buys 200 pounds of weight plates for $1.2 per pound. A 200-pound weight vest would cost $700 but there is a $100 discount. How much does he save with his vest?
Answer: The weight plates cost 200 * 1.2 = $240. So his vest cost 250 + 240 = $490. He could get the other vest for 700 - 100 = $600. So he saved 600 - 490 = $110. The answer is 110.
[Question]Joy has 30 pencils, and Colleen has 50 pencils. If they bought the pencils at $4 each at the store, how much more money did Colleen pay than Joy for her pencils?
[Answer]The number of pencils that Colleen has more than Joy is 50 - 30 = 20 pencils. If each pencil was sold at $4 each, Colleen paid $4 * 20 = $80 more for the 20 extra pencils she has more than Joy. The answer is 80.
[Question]Rachel is 4 years older than Leah. If the sum of their ages is 34, how old is Rachel?
[Answer]
If Rachel and Leah have the same age, then the sum of their ages would be 34 - 4 = 30. So Leah would be 30 / 2 = 15 years old. Hence, Rachel is 15 + 4 = 19 years old. The answer is 19.
