Q: Gina is considered a bad tipper because she tipped 5%. If good tippers tip at least 20%, how many more cents than normal would Gina have to tip on a bill of $26 to be considered a good tipper?
A: First convert the bill amount to cents: $26 * 100 cents / dollar = 2600 cents. Then multiply that amount by 5% to find the amount Gina normally tips: 2600 cents * 5% = 130 cents. Then multiply the bill amount by 20% to find the amount of a good tip: 2600 cents * 20% = 520 cents. Then subtract the good tip amount from the bad tip amount to find how much more Gina needs to tip: 520 cents - 130 cents = 390 cents. The answer is 390.
Question: This morning, farmer Rita's workers collected 30,000 gallons of milk and chilled it in a storage tank. They then spent the next 4 hours pumping milk at a rate of 2,880 gallons/hour from the storage tank into a milk tanker. For the next 7 hours, the workers added more milk into the storage tank, at a rate of 1,500 gallons per hour. How many gallons of milk were left in the storage tank?
Answer: In the first 4 hours, the milk tanker got 4 hours * 2880 gallons / hour = 11,520 gallons. Thus, the storage tank was left with 30,000 gallons - 11,520 gallons = 18,480 gallons. For the next 7 hrs, the workers added 1,500 gallons / hour * 7 hours = 10,500 gallons. The total therefore is 18,480 gallons + 10,500 gallons = 28,980 gallons. The answer is 28980.
[Question]There are 18 green leaves on each of the 3 tea leaf plants. One-third of them turn yellow and fall off on each of the tea leaf plants. How many green leaves are left on the tea leaf plants?
[Answer]In total, the 3 tea leaf plants have 18 x 3 = 54 green leaves. One - third of the yellow leaves falling off of all plants is 54 / 3 = 18. The number of remaining green leaves on the plants is 54 - 18 = 36. The answer is 36.
Q: Noah has two closets. Each closet can fit 1/4 as much as Ali's closet, which can fit 200 pairs of jeans. How many jeans can both Noah's closets fit?

Question: At Snowflake Plastics, each employee gets 10 sick days and 10 vacation days per year. If Mark uses half his allotment of both types of days in a year, how many hours' worth of days does he have left if each day covers an 8-hour long workday?
Answer:
First, we add the two types of days together to find 10 + 10 = 20 days in total between the two types. We then divide this number in half to find Mark's remaining number of days, getting 20 / 2 = 10 days remaining. Since each day counts as 8 hours, we multiply 10 * 8 = 80 hours' worth of days remaining for Mark. The answer is 80.
