Liz sold her car at 80% of what she originally paid. She uses the proceeds of that sale and needs only $4,000 to buy herself a new $30,000 car. How much cheaper is her new car versus what she originally paid for her old one?
Let's think: If Liz needs only $4,000 to buy a new $30,000 car, that means she has $30,000 - $4,000 = $26,000 from the proceeds of selling her old car. If she sold her car at 80% of what she originally paid for and sold it for $26,000 then she originally paid $26,000 / 80% = $32,500 for her old car. If she paid $32,500 for her old car and the new one is $30,000 then, the new one is $32,500 - $30,000 = $2,500 cheaper.. The answer is: 2500.

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?
Let's think: 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.

A group of 4 fruit baskets contains 9 apples, 15 oranges, and 14 bananas in the first three baskets and 2 less of each fruit in the fourth basket. How many fruits are there?
Let's think: For the first three baskets, the number of apples and oranges in one basket is 9 + 15 = 24. In total, together with bananas, the number of fruits in one basket is 24 + 14 = 38 for the first three baskets. Since there are three baskets each having 38 fruits, there are 3 * 38 = 114 fruits in the first three baskets. The number of apples in the fourth basket is 9 - 2 = 7. There are also 15 - 2 = 13 oranges in the fourth basket. The combined number of oranges and apples in the fourth basket is 13 + 7 = 20. The fourth basket also contains 14 - 2 = 12 bananas. In total, the fourth basket has 20 + 12 = 32 fruits. The four baskets together have 32 + 114 = 146 fruits.. The answer is: 146.

Daphney buys 5 kg of potatoes at the supermarket. If 2 kg of potatoes costs $6, how much will she pay?
