[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.
So the answer is 2900.

[Question]: Celine collected twice as many erasers as Gabriel did. Julian collected twice as many erasers as Celine did. If they collected 35 erasers in total, how many erasers did Celine collect?
[Answer]: Let x represent the number of erasers Gabriel collected. Celine collected 2 * x erasers. Julian collected 2 * x * 2 = 4 * x erasers. In total, Gabriel, Celine and Julian collected x + 2 * x + 4 * x = 7 * x erasers. 7 * x = 35. x = 5. Celine collected 5 * 2 = 10 erasers.
So the answer is 10.

[Question]: Lloyd, Mark, and Michael have their Pokemon cards collection. Currently, Mark has thrice as many cards as Lloyd but has 10 fewer cards than Michael. If Michael has 100 cards now, how many more cards should they collect so that all three of them will have a total of 300 cards?
[Answer]:
Mark has 10 fewer cards than Michael so Mark has 100 cards - 10 cards = 90 cards. So, Lloyd has 90 cards / 3 = 30 cards. All three of them have 90 cards + 30 cards + 100 cards = 220 cards. Thus, they need to collect 300 cards - 220 cards = 80 more cards.
So the answer is 80.
