[Question]A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
[Answer]After one day of sailing, 2 / 5 * 400 = 160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400 - 160 = 240 pounds. After another 2 days of sailing, 3 / 5 * 240 = 144 pounds of food had been used. The total number of supplies remaining in the ship is now 240 - 144 = 96 pounds. The answer is 96.
Q: Ice cream costs $2.00 and toppings cost $0.50 per topping. How much does a sundae with 10 toppings cost?
A: First find the total cost of the toppings: 10 toppings * $0.50 / topping = $5.00. Then add that amount to the cost of the ice cream: $5.00 + $2.00 = $7.00. The answer is 7.
Question: Gondor is a technician, he earns $10 from repairing a phone and $20 from repairing a laptop. If he was able to repair 3 phones last Monday, 5 phones last Tuesday, 2 laptops on Wednesday, and 4 laptops last Thursday, how much does he earn in total?
Answer: Gondor was able to repair a total of 3 + 5 = 8 phones from Monday to Tuesday. And the total amount he earned is $10x8 = $80. He was able to repair a total of 2 + 4 = 6 laptops from Wednesday to Thursday. So, the total amount he earned is $20x6 = $120. Therefore, the total amount he earned is $120 + $80 = $200. The answer is 200.
[Question]Mary bought a packet of 1500 stickers. She shared them between Susan, Andrew and Sam in the ratio 1:1:3 respectively. If Sam gave Andrew two-thirds of his own share, how many stickers does Andrew now have?
[Answer]The sum of the ratio is 1 + 1 + 3 = 5, therefore each part is 1500 / 5 = 300 stickers. Sam got 3 parts for a total of 3 * 300 = 900 stickers. He gave two - thirds of this which is 900 * (2 / 3) = 600 stickers to Andrew. Andrew had one part already, which is 1 * 300 = 300. Andrew now has a total of 300 + 600 = 900 stickers. The answer is 900.
Q: A trolley driver picked up 10 people on his 1st stop. On the next stop, 3 people got off and twice as many people from the 1st stop got on. On the third stop, 18 people got off and 2 got on. How many people are currently on the trolley?
A: Between the trolley driver and his first 10 customers, there are 1 + 10 = 11 people are currently on the trolley. On his first stop, 10 people go on and twice as many people got on at the second stop so 10 * 2 = 20 people got on at the second stop. So at the second stop he had 11 people on board, 3 got off and 20 got on so he now has 11 - 3 + 20 = 28 people. At his third stop 18 people got off and 2 got on so in total there are 28 - 18 + 2 = 12 people on the trolley. The answer is 12.
Question: Jim is wondering how many miles each gallon of gas gets him. His gas tank is 12 gallons. He has 2/3 of a tank left after he drives to and from work, which is 10 miles away from his house. How many miles per gallon does he get?
Answer:
He used 1 / 3 of his tank because 1 - (2 / 3) = 1 / 3. He used 4 gallons of gas because 12 x (1 / 3) = 4. He drove 20 miles because 2 x 10 = 20. He gets 5 miles per gallon because 20 / 4 = 5. The answer is 5.
