Question: Duke was at a garage sale when he spotted DVDs on sale. They were separated by price into 2 different boxes. In the first box, he found 10 movies that he wanted. These were $2.00 apiece. The second box was marked $5 each and he found 5 movies he wanted. What was the average price of each of the DVDs he bought?
Answer: In the first box he bought 10 DVDs at $2.00 each, so he paid 10 * 2 = $20.00. In the second box he bought 5 DVDs at $5.00 each, so he paid 5 * 5 = $25.00. He bought 10 + 5 = 15 DVDs. He spent $20 + $25 = $45.00. The average price of each DVD is $45 / 15 = $3.00 each. The answer is 3.

Question: Brady gets paid 70 cents for each recipe card he transcribes. He also gets a 10 dollar bonus each time he transcribes 100 cards. If he transcribes 200 cards how much will he earn including bonuses?
Answer: For 200 cards he earns .70 * 200 = 140 dollars. Since he transcribes 200 cards his bonus is 10 * 2 = 20 dollars. In total he earns 140 + 20 = 160 dollars. The answer is 160.
[Question]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?
[Answer]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 answer is 67500.

Lilibeth picks 6 x 50 = 300 strawberries. There are 1 + 3 = 4 of them who are picking strawberries. Therefore, they pick a total of 300 x 4 = 1200 strawberries. The answer is 1200.
