[Question]Tobias is a tractor salesman. His salary is based on the number of tractors he sells. For every red tractor he sells, he gets paid 10% of the sales price for each tractor. For every green tractor he sells, he gets paid 20% of the sales price for each tractor. This week, he sold 2 red tractors and 3 green tractors. The price of a single red tractor is $20,000. This week, Tobias's salary was $7000. What is the full price of a single green tractor, in dollars?
[Answer]For red tractors, 10% of the sales price is 10 / 100 * $20,000 = $2000. By selling two red tractors, he earned 2 * $2000 = $4000. Thus, of the $7000 salary he was paid this week, $7000 - $4000 = $3000 is from sales of green tractors. And since he sold three green tractors, the commission for the sale of a single green tractor is $3000 / 3 = $1000,. If $1000 is 20% of the full price, then the full price for a green tractor is (100 / 20) * $1000 = $5000. The answer is 5000.
Q: The sum of the three angles of a triangle equals 250. The left angle is twice the right angle's value, and the right angle is 60 degrees. Find the value of the top angle?
A: Since the left angle is twice the value of the right angle, the left angle is 60 * 2 = 120 degrees. The total value of the left and right angles is 120 + 60 = 180 degrees. Since the sum of the three angles is equal to 250, the other angle has a value of 250 - 180 = 70 degrees. The answer is 70.
Question: It takes Nissa 10 seconds to clip each of her cats' nails. 90 seconds to clean each of her ears, and 5 minutes to shampoo her. If the cat has four claws on each foot, how many seconds does grooming her cat take total?
Answer: First find the total number of claws the cat has: 4 claws / foot * 4 feet = 16 claws. Then find the total time Nissa spends cutting the claws: 16 claws * 10 seconds / claw = 160 seconds. Then find the total time she spends cleaning the cats' ears: 90 seconds / ear * 2 ears = 180 seconds. Then find how long the shampooing takes in seconds: 5 minutes * 60 seconds / minute = 300 seconds. Then add the time she spends on each task to find the total time she spends grooming the cat: 160 seconds + 180 seconds + 300 seconds = 640 seconds. The answer is 640.
[Question]Peter has a plan to take his family on a vacation to Germany. He needs $5,000 to cover all the spending for the travel, and he has $2,900 in savings right now. If he can save up $700 each month, how many months does he need to wait to reach his goal?
[Answer]Peter needs $5,000 – $2,900 = $2,100 in total. He will have to wait for $2100 ÷ $700 / month = 3 months to reach his goal. The answer is 3.
[Question]In a math test, Mark scored twice as much as the least score. If the highest score is 98 and the range of the scores is 75, what was Mark's score?
[Answer]
The range of scores is the difference between the highest and the least score so 75 = 98 - least score. Then the least score = 98 - 75 = 23. Mark scored twice as much as the least score which is 2 * 23 = 46. The answer is 46.
