Q: Iain has 200 pennies. He realizes that 30 of his pennies are older than he is. If he wishes to get rid of these pennies and then throw out 20% of his remaining pennies, how many will he have left?
A: Start with taking out the older pennies 200 pennies - 30 pennies = 170 pennies. Take the 170 pennies * .20 = 34. 170 pennies - 34 pennies = 136 pennies. The answer is 136.
Question: Lee wants to propose marriage to Sierra. He wants to follow the adage that you should spend two months' salary on the ring. He earns $60,000 per year in salary and can save $1000 per month. How long will it take before he can propose to Sierra?
Answer: Lee currently earns $60,000 / 12 months = $5,000 per month. The engagement ring will cost him 2 * $5,000 = $10,000. This means that it will take Lee $10,000 / $1,000 = 10 months to save enough money before he can propose. The answer is 10.
[Question]On a monthly basis, Esperanza pays $600 in rent, 3/5 as much money on food as she pays on rent and her mortgage bill costs three times the amount of money she spends on food. If she saves $2000 and also pays the equivalent of 2/5 of her savings in taxes, calculate her gross monthly salary.
[Answer]Esperanza pays 3 / 5 * $600 = $360 on food. She also spends 3 * $360 = $1080 on mortgage bills. Her expenses in taxes amount to 2 / 5 * $2000 = $800. Esperanza's total monthly expenses are $800 on taxes + $1080 on mortgage bills + $360 on food + $600 on rent = $2840. Her gross salary is $2840 for expenses + $2000 on savings = $4840. The answer is 4840.

A: Cassie needs to drink 8 * 12 = 96 ounces of water to drink 12 cups a day. Thus, Cassie needs to refill her water bottle 96 / 16 = 6 times a day. The answer is 6.
Question: Megan is making food for a party. She has to spend 20 minutes preparing one dish in the oven. Each dish can feed 5 people. She spends 2 hours preparing as many of these dishes as she can for the party. How many people can she feed with these dishes?
Answer: First, we need to determine the total amount of minutes available for cooking. We do this by performing 2 * 60 = 120, as there are 60 minutes in an hour. Now that we know we have 120 minutes, we then divide the preparation time into the total amount of time by performing 120 / 20 = 6 dishes capable of being made. Since each dish can feed 5 people, we find the total number of people fed by performing 5 * 6 = 30 people. The answer is 30.
Q: The price of buying a wooden toy at the new Craftee And Best store is $20, and the cost of buying a hat is $10. If Kendra went to the shop with a $100 bill and bought two wooden toys and three hats, calculate the change she received.
A:
When Kendra bought 2 toys, she paid 2 * $20 = $40. Since the price of a hat is $10, when Kendra bought 3 hats, she paid 3 * $10 = $30. The total costs for the hats and wooden toys Kendra bought is $40 + $30 = $70. From the $100 bill, Kendra received change worth $100 - $70 = $30. The answer is 30.
