Question: Hazel put up a lemonade stand. She sold half her lemonade to a construction crew. She sold 18 cups to kids on bikes. She gave away half that amount to her friends. Then she drank the last cup of lemonade herself. How many cups of lemonade did Hazel make?
Answer: Hazel sold 18 cups of lemonade to kids on bikes and gave half that amount, or 18 / 2 = 9 cups, away to friends. Hazel sold 18 cups + gave away 9 cups + drank 1 cup = 28 cups. Since Hazel sold half her lemonade to a construction crew, that means the 28 cups she sold to kids on bikes, gave away to friends and drank herself are the other half, so she sold 28 cups to the construction crew. In all, Hazel sold 28 + 28 = 56 cups of lemonade. The answer is 56.
[Question]To eat to when she gets full, Michaela needs 20 oranges. Cassandra needs twice as many oranges as Michaela to eat until she gets full. If they picked 90 oranges from the farm today, how many oranges would remain after they've both eaten until they were full?
[Answer]Since Michaela needs 20 oranges to eat to her full, and Cassandra eats twice as much to have her full, Cassandra needs 2 * 20 = 40 oranges to eat. They eat 20 + 40 = 60 oranges together to have their fill. If they picked 90 oranges today, after eating 60 together, 90 - 60 = 30 oranges would remain. The answer is 30.
Q: Mrs. Smith wanted to buy wears worth $500. She went to a boutique with the $500 but by the time she had picked out everything she liked, she realized that she would need two-fifths more money than she had. If the shop owner gave her a discount of 15%, how much more money will she still need?
A: Two fifths of $500 is (2 / 5) * $500 = $200. She needed $200 more than $500 which is $200 + $500 = $700. 15% of $700 is (15 / 100) * $700 = $105. She was given a $105 discount so she has to pay $700 - $105 = $595. She would still need $595 - $500 = $95. The answer is 95.
Question: Olivia's insurance premium starts out at $50/month. It goes up 10% for every accident and $5/month for every ticket. If she gets in one accident and gets 3 tickets, what's her new insurance premium?
Answer: First find the increase due to the accident: $50 * 10% = $5. Then find the total increase due to the tickets: $5 / ticket * 3 tickets = $15. Then add both increases to the base price to find the new price: $50 + $5 + $15 = $70. The answer is 70.
[Question]Sammy can eat 15 pickle slices. His twin sister Tammy can eat twice as much as Sammy. Their older brother Ron eats 20% fewer pickles slices than Tammy. How many pickle slices does Ron eat?
[Answer]Tammy can eat twice as many pickle slices as Sammy who eats 15 so Tammy can eat 15 * 2 = 30 pickle slices. Ron eats 20% fewer pickle slices than Tammy who eats 30 pickle slices so that's .20 * 30 = 6 fewer slices than Tammy. Tammy eats 30 slices and Ron eats 6 less, then Ron eats 30 - 6 = 24 pickle slices. The answer is 24.

The amount before the deduction is $430 + $190 = $620. The amount paid to the seller after the discount is $620 - $100 = $520. The answer is 520.
