Question: An internet provider gives a 5% discount if the customer pays before the 25th day of the month. If the monthly internet rate is $50, how much did the customer pay in all for 4 months if he paid every 25th of the month?
Answer: The 5% discount amounts to $50 x 5 / 100 = $2.50. So the total discount given to the customer for 4 months was $2.50 x 4 = $10. The customer was supposed to pay $50 x 4 = $200 in all for 4 months without discount. Since the customer is entitled to the discount, then he only paid a total of $200 - $10 = $190 for 4 months. The answer is 190.
[Question]Robbie is tracking his nutrition intake per week. He eats 3 cups of rice in the morning, 2 cups of rice in the afternoon, and 5 cups of rice in the evening. If a cup of rice has 10 grams of fat, how many grams of fat does Robbie get in a week?
[Answer]Robbie gets 3 x 10 = 30 grams of fat every morning. He gets 10 x 2 = 20 grams of fat every afternoon. And he gets 5 x 10 = 50 grams of fat every evening. So, the total grams of fat he gets every day is 50 + 30 + 20 = 100. Therefore, the total grams of fat he gets every week is 100 x 7 = 700. The answer is 700.
Q: James takes up dancing for fitness. He loses twice as many calories per hour as he did when he was walking. He dances twice a day for .5 hours each time and he does this 4 times a week. He burned 300 calories an hour walking. How many calories does he lose a week from dancing?
A: He burns 2 * 300 = 600 calories an hour. He dances for .5 * 2 = 1 hour per day. So he burns 600 * 1 = 600 calories per day. So he burns 600 * 4 = 2400 calories per week. The answer is 2400.

[Question]Hansel makes $30,000 a year and just received a 10% raise. Gretel makes the same amount as Hansel but received a 15% raise. How much more money will Gretel make compared to Hansel?
[Answer]
Hansel makes $30,000 and received a 10% raise so his raise is 30,000 * .10 = $3,000.00. Hansel now makes 30,000 + 3,000 = $33,000 a year. Gretel makes $30,000 and received a 15% raise so her raise is 30,000 * .15 = $4,500.00. Gretel now makes 30,000 + 4,500 = $34,500 a year. If Gretel makes $34,500 a year and Hansel makes $33,000 then Gretel makes 34,500 - 33,000 = $1,500 more a year than Hansel. The answer is 1500.
