Answer the following question.
Lisa bought a new iPhone for $1000. She bought a phone contract that costs $200/month, a case that costs 20% of the cost of the phone, and headphones that cost half as much as the case. How much will Lisa spend on her phone in the first year?
Step-by-step reasoning process: First find the cost of the case: $1000 * 20% = $200. Then find the cost of the headphones: $200 / 2 = $100. Then find how much the phone contract will cost over a year: $200 / month * 12 months / year = $2400. Finally, add the cost of the phone, accessories, and plan over the first year to find the total: $2400 + $100 + $200 + $1000 = $3700.
The answer is 3700.

Answer the following question.
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?
Step-by-step reasoning process: 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 answer is 9400.

Answer the following question.
Max works for a delivery company as a courier. During one working day, he can deliver a maximum of 35 packages. One week, Max delivered the maximum number of packages, only twice. On two other days, Max unloaded a total of 50 packages, and on one day he unloaded only one-seventh of the maximum possible daily performance. On the last two days, the sum of the packages transported was only fourth-fifth of the maximum daily performance. How many more packages could Max deliver during that week, if he would work at maximum performance?
Step-by-step reasoning process: Max can deliver a maximum of 35 * 7 = 245 packages in one week. For two days Max has carried the maximum number of packages, which in total means 2 * 35 = 70 packages. One day Max has carried only 1 / 7 of the maximum capacity, that is 1 / 7 * 35 = 5 packages. On two other days, Max delivered only 4 / 5 * 35 = 28 packages. That means, Max could deliver 245 - 28 - 5 - 70 - 50 = 92 more packages.
The answer is 92.
