[Question]Jane is trying to decide whether to buy a house or a trailer. A house costs $480,000 and a trailer costs $120,000. Each loan will be paid in monthly installments over 20 years. How much more is the monthly payment on the house compared to the trailer?
[Answer]First find how many months the loans last: 20 years * 12 months / year = 240 months. Then divide the cost of the house by the number of payments to find the monthly payment before interest: $480,000 / 240 months = $2000 / month. Then do the same thing to find the monthly payment before interest on the trailer: $120,000 / 240 months = $500 / month. Then subtract the cost of the trailer payment from the cost of the house payment to find the difference: $2000 / month - $500 / month = $1500 / month. The answer is 1500.

[Question]Martha receives a daily allowance of $12. She decides to save half of this amount every day. In the first week she kept her commitment with the exception of one day when she saved only a quarter of this amount. How much has she saved at the end of this week?
[Answer]Half of $12 is (1 / 2) * $12 = $6. There are 7 days in a week so if she saved half every day except one then she saved half for 7 - 1 = 6 days. She saved $6 for 6 days for a total of $36. A quarter of $12 is (1 / 4) * $12 = $3. She saved a quarter once for a total savings of $3 + $36 = $39. The answer is 39.

[Question]Patricia is making a highlight film about her basketball team. She recorded video of every player and plans to put it all together in a longer movie. She has 130 seconds of the point guard, 145 seconds of the shooting guard, 85 seconds of the small forward, 60 seconds of the power forward, and 180 seconds of the center. How on average, how many minutes does each player get?
[Answer]The total movie is 600 seconds long because 130 + 145 + 85 + 60 + 180 = 600. The total movie is 10 minutes long because 600 / 60 = 10. On average each player gets 2 minutes because 10 / 5 = 2. The answer is 2.
