Question: James invests $2000 a week into his bank account. He had $250,000 in his account when the year started. At the end of the year, he gets a windfall that is worth 50% more than what he has in his bank account. How much money does he have?
Answer: He deposited 2000 * 52 = $104,000 into his account. So he has 250000 + 104000 = $354,000. His windfall is worth .5 * 354,000 = $177,000 more than his current account. That means he got 177,000 + 354,000 = $531,000. So he had a total of 531,000 + 354,000 = $885,000. The answer is 885000.

Question: If olivine has 5 more precious stones than agate and diamond has 11 more precious stones than olivine, how many precious stones do they have together if agate has 30 precious stones?
Answer:
Since Agate has 30 precious stones and Olivine has 5 more precious stones, then Olivine has 30 + 5 = 35 precious stones. The total number of stones Olivine and Agate has is 35 + 30 = 65. Diamond has 11 more precious stones than Olivine, who has 35 stones, meaning Diamond has 35 + 11 = 46 precious stones. In total, they all have 65 + 46 = 111 precious stones. The answer is 111.
