Q: The number of Oreos and cookies in a box is in the ratio 4:9. Zane bought each Oreo at $2 and each cookie at $3. How much more money did Zane spend on buying the cookies than buying the Oreos if the total number of items in the box is 65?
A: The total ratio representing the number of cookies and Oreos that Zack bought is 4 + 9 = 13. The fraction representing the number of Oreos Zane bought is 4 / 13, and since the total number of items in the box is 65, Zane bought 4 / 13 * 65 = 20 Oreos. If Zane bought 20 Oreos at $2 each, the total cost of buying Oreos is $2 * 20 = $40. Since the total number of items in the box is 65, and there are 20 Oreos in the box, the number of cookies in the box is 65 - 20 = 45. The cost of buying the cookies at $3 each is 45 * $3 = $135. If the Oreos cost $40 to buy, Zane used $135 - $40 = $95 more to buy Cookies than Oreos. The answer is 95.
Question: Sidney has 4 kittens and 3 adult cats. She has 7 cans of cat food. Each adult cat eats 1 can of food per day. Each kitten eats 3/4 of a can per day. How many additional cans of food does Sidney need to buy to feed all of her animals for 7 days.
Answer: Sidney has 3 adult cats * 1 can of food = 3 cans of food per day. Sidney's adult cats will need 3 cans * 7 days = 21 cans for the week. Sidney has 4 kittens * 3 / 4 cup of food = 3 cans of food per day. Sidney's kittens will need 3 cans * 7 days = 21 cans for the week. Sidney will need to buy 21 cans + 21 cans - 7 cans = 35 cans. The answer is 35.
[Question]Four small boxes can fit in one big box. If 50 big boxes can fit four small boxes each, each having 40 candles, calculate the total number of candles in all small boxes.
[Answer]If 50 big boxes are fit 4 small boxes each, the number of small boxes is 4 * 50 = 200. Since the small boxes have 40 candles each, there are 40 * 200 = 8000 candles in total. The answer is 8000.
Q: Dexter went to the mall and saw that Apple products are on sale. He wants to buy an iPhone 12 with a 15% discount and an iWatch with a 10% discount. The price tag shows that an iPhone 12 costs $800 while an iWatch costs $300. Upon check out, he will receive a further 2% cashback discount. How much would the items cost in total after the discount and cashback?
A: The discount for an iPhone 12 is $800 x 15 / 100 = $120. So, the iPhone will now cost $800 - $120 = $680. The discount for an iWatch is $300 x 10 / 100 = $30. So, the iWatch will now cost $300 - $30 = $270. The total cost of the iPhone and iWatch is $680 + $270 = $950. The cashback will be $950 x 2 / 100 = $19. Thus, Dexter will only pay $950 - $19 = $931. The answer is 931.
