Step-by-step reasoning process: The first 3 pieces each cost 45000 / 3 = $15,000. So the next piece was 15,000 * .5 = $7,500 more expensive. That means it cost 15,000 + 7,500 = $22,500. That means in total he spent 45,000 + 22,500 = $67,500.
The question and answer:
Question and answer: John decides to start collecting art. He pays the same price for his first 3 pieces of art and the total price came to $45,000. The next piece of art was 50% more expensive than those. How much did all the art cost?
The answer is 67500

Step-by-step reasoning process: If the red bus is 48 feet long, the orange car is 48 / 4 = 12 feet long. Since the length of the orange car is 3.5 times shorter than a yellow bus, the yellow bus is 3.5 * 12 = 42 feet long. If sitting next to each other, the driver of the yellow car will see 48 - 42 = 6 feet of the red bus.
The question and answer:
Question and answer: The length of a red bus is four times the length of an orange car. The length of the orange car is also 3.5 times shorter than the length of a yellow bus. If the yellow bus and red bus are sitting next to each other, what length of the red bus may the yellow bus driver see if the red bus is 48 feet long?
The answer is 6

Step-by-step reasoning process: Two pieces of snickers cost $1.5 x 2 = $3. One pack of M&M's costs $3 so 3 packs cost $3 x 3 = $9. The total amount that she needs to pay is $3 + $9 = $12. Julia gave the cashier $10 x 2 = $20. So, her change is $20 - $12 = $8.
The question and answer:
Question and answer:
In a grocery store, Julia bought 2 pieces of Snickers and 3 packs of M&M's. If each piece of Snickers costs $1.5 and a pack of M&M's has the same cost as 2 Snickers, how much is Julia's change if she gave the cashier 2 $10 bills?
The answer is 8
