Give the step-by-step reasoning process and then the final answer. Jack has 42 pounds, 11 euros, and 3000 yen. If there are 2 pounds per euro and 100 yen per pound, how much does Jack have in yen?
First convert the euros to pounds: 11 euros * 2 pounds / euro = 22 pounds. Then add that amount to the amount Jack has in pounds: 22 pounds + 42 pounds = 64 pounds. Then convert the pounds to yen: 64 pounds * 100 yen / pound = 6400 yen. Then add that amount to the amount Jack has in yen: 6400 yen + 3000 yen = 9400 yen.
The final answer: 9400.
