Question: Barney washes his kitchen towels once a week. He owns eighteen towels and uses two at a time that he changes to clean towels daily. He missed one week of laundry. How many days the following week will Barney not have clean towels?
Answer: Barney uses 2 clean towels every day, so he uses 2 * 7 = 14 towels a week. He missed one week of laundry, so he would need 2 * 14 = 28 towels for 2 weeks. He owns 18 towels, so he has 28 - 18 = 10 less than he needs. Thus, Barney will not have clean towels on 10 / 2 = 5 days. The answer is 5.
[Question]While buying DVDs at the store, Maria received a 25% discount. If the discount she received is $40, how much did she pay in total?
[Answer]Since 100 percent represent the original price, and she received a 25% discount which is $40, the original price is 100 / 25 * 40 = 160. Maria paid $160 - $40 = $120 after receiving the twenty - five percent discount. The answer is 120.
Q: Marco uses a fifth of an ounce of dry tea leaves to brew his morning cup of tea each day. He buys tea leaves in boxes of 28 ounces. How many weeks of daily tea does Marco get from a box?
A: Marco gets 28 / 1 / 5 = 28 * 5 = 140 cups of tea from a box. At 7 days a week, Marco gets 140 / 7 = 20 weeks of daily tea from a box. The answer is 20.
Question: Mica went to the grocery store and bought 2 kilograms of pasta that costs $1.5; 1/4 kilogram of ground beef costs $8 for 1 kilogram; two jars of pasta sauce costs $2 per jar. Mica also wants to buy a $6 Quesadilla for snacks. How much money should she have with her to buy all those?
Answer: Two kilograms of pasta cost $1.5 x 2 = $3. One - fourth kilogram of ground beef cost $8 x 1 / 4 = $2. Two jars of pasta sauce cost $2 x 2 = $4. The total cost for the pasta, beef, and sauce is $3 + $2 + $4 = $9. Since Mica also wants to buy Quesadilla, she should have $9 + $6 = $15. The answer is 15.
[Question]Gary bought his first used car for $6,000. Gary borrowed the money from his dad who said he could pay him back the full amount over 5 years. Gary decided he would pay his dad back the full amount in 2 years. How much more is Gary spending per month to pay the loan off in 2 years instead of 5?
[Answer]A full year has 12 months. So 2 years is 2 * 12 = 24 months. The loan amount is $6,000 that he will repay in 24 months so 6000 / 24 = $250 per month. If he paid his dad back in 5 years that 5 * 12 = 60 months. $6,000 loan spread out over 60 months is 6000 / 60 = $100 per month. To pay it off in 2 years instead of 5, Gary is paying 250 - 100 = $150 more per month. The answer is 150.
