Q: Anna's mom gave her $10.00 to buy anything she wanted from the candy store. Anna bought 3 packs of chewing gum for $1.00 each, 5 chocolate bars at $1 each and 2 large candy canes for $0.50 each. How much money did Anna have left?
A: Anna bought 3 packs of chewing gum that were $1 each for a total of 3 * 1 = $3. Anna bought 5 chocolate bars that were $1 each for a total of 5 * 1 = $5. Anna bought 2 large candy canes that were $.50 each for a total of 2 * .50 = $1. The total amount spent was $3 + $5 + $1 = $9.00. Anna had $10 to start and spent $9.00 so she had $10 - $9.00 = $1.00 left. The answer is 1.
Question: On Saturday morning, Renata had $10 to spend. She first went and made a $4 donation in exchange for a ticket to the local charity draw. When the draw was done, she was declared the winner of the 5th prize of $90. Excited, she quickly dashed to play slots at one of the casinos in Atlantic City. Unfortunately, she lost $50 at the first slot machine, $10 at the second and $5 at the last one. Dejected, she decided to take a long walk. She soon grew thirsty and entered the first gas station she saw. She picked a $1 bottle of water and while paying for it, she bought a $1 lottery ticket. To her utter delight, she won an instant prize of $65. How much money did Renata end up having?
Answer: After the charity ticket purchase on Saturday morning, Renata remained with 10 - 4 = 6 dollars. Adding the prize money give her 6 + 90 = 96 dollars. At the casino, she lost 50 + 10 + 5 = 65 dollars. Thus far, Renata remained with 96 - 65 = 31 dollars. The amount she spent on the bottle of water and lottery ticket is 1 + 1 = 2 dollars. This means that she remained with 31 - 2 = 29 dollars. Since she won 65 dollars, Renata’s ended up having 29 + 65 = 94 dollars. The answer is 94.
[Question]Happy Cattle Ranch is home to 200 cows. Every year, the mother cows have enough calves that the number of cows the rancher owns rises by half the number of cows living on the ranch. If the rancher does not buy or sell any cows, how many cows will the rancher own on Happy Cattle Ranch in two years?
[Answer]In one year, the rancher will have 200 + 200 / 2 = 200 + 100 = 300 cows. In two years, the rancher will have 300 + 300 / 2 = 300 + 150 = 450 cows. The answer is 450.
Q: A basketball team won 40 games in their last competition. In the next competition, they won 5/8 times as many games as they won in their first competition. In the third competition, they won the same number of games as the sum of the first and second competition winnings. Calculate the total number of wins they had in the three competitions.
A: If they won 40 games in the first competition, they won 5 / 8 * 40 = 25 games in their second season. In the third competition, they won games equal to the sum of the games they won in the last two competitions, which is 25 + 40 = 65 games. Since the total number of games they won in the first two competitions is 65, and they won 65 more in the third competition, they won a total of 65 + 65 = 130 in all competitions. The answer is 130.
Question: Stuart is going on a cross-country trip and wants to find the fastest route. On one route the total distance is 1500 miles and the average speed is 75 MPH. On the second trip, the total distance is 750 but the average speed is 25 MPH. How long does his trip take if he goes on the fastest route?
Answer: The first route will take 20 hours because 1,500 / 75 = 20. The second route will take 30 hours because 750 / 25 = 30. The fastest route takes 20 hours because 20 < 30. The answer is 20.
Q: Heather helps her neighbour pick weeds out of her garden. She gets paid 5 cents for every weed she picks. On average, how many seconds can she take to pick a weed if she wants to earn $10 an hour?
A:
In an hour, she needs to earn $10 * 100 cents / $1 = 1000 cents. In an hour, she must pick 1000 cents / 5 cents = 200 weeds. There are 1hr * (60 minutes / 1 hr) = 60 minutes in an hour. There are 60 minutes * (60 seconds / 1 minute) = 3600 seconds in an hour. She has 3600 seconds / 200 = 18 seconds to pick each weed. The answer is 18.
