Question: Josh has $300 in his wallet, and $2000 invested in a business. If the business's stock price rises 30% and then he sells all of his stocks, how much money will he have in his wallet?
Answer: If the business's stock price rises 30%, then his share on the company is worth 30% multiplied by $2000 plus $2000 that he already had. That results in 30% * $2000 + $2000 = $600 + $2000 = $2600. Since he already had $300, with $2600 more he will have $300 + $2600 = $2900. The answer is 2900.
[Question]A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers?
[Answer]In the morning, the store gives away 19 bikes * 2 bike clamps = 38 bike clamps. In the afternoon, they give away 27 bikes * 2 bike clamps = 54 bike clamps. So in total, the store has given away 38 + 54 = 92 bike clamps. The answer is 92.
Q: Tim decides to start selling necklaces he makes. He uses 10 charms to make each necklace. Each charm cost $15. He sells the necklace for $200. How much profit does he make if he sells 30?
A: Each necklace cost 10 * 15 = $150 to make. So he makes a profit of 200 - 150 = $50 each. So his total profit is 50 * 30 = $1500. The answer is 1500.
Question: At the same store, Peter bought 2 pairs of pants and 5 shirts for $62 total, and Jessica bought 2 shirts for $20 total. Each pair of pants cost the same price, and each shirt cost the same price. How much does 1 pair of pants cost?
Answer: The shirts each cost $20 / 2 shirts = $10. Let X be the pants' cost. Peter bought 2 pairs of pants and 5 shirts for 2 * X + 5 shirts * $10 / shirt = $62. Subtracting $50 from both sides, we get 2 * X = $12. Dividing both sides by 2, we get X = $6. The answer is 6.
[Question]A park has three colors of flowering crepe myrtle trees planted: red, white, and pink. When they bloom, a third of them are pink, but only two are red. Most of them are white. There are 42 crepe myrtle trees in the park. How many have white flowers when they bloom?
[Answer]The park has 42 / 3 = 14 pink crepe myrtle trees. It has 2 red trees, so it has 14 + 2 = 16 pink and red trees. Therefore, there are 42 - 16 = 26 crepe myrtle trees that have white flowers when they bloom in the park. The answer is 26.
