[Question]Matt has six cats and half of them are female. If each female cat has 7 kittens, and Matt sells 9 of them, what percentage of his remaining cats are kittens (rounded to the nearest percent)?
[Answer]First find the number of cats that are females: 6 cats / 2 = 3 cats. Then find the total number of kittens born: 7 kittens / cat * 3 cats = 21 kittens. Then subtract the 9 kittens that were sold: 21 kittens - 9 kittens = 12 kittens. Then add the number of kittens to the number of adult cats to find the total number of cats: 12 kittens + 6 cats = 18 cats. Then divide the number of kittens by the total number of cats and multiply by 100% to find the percentage of cats that are kittens: 12 kittens / 18 cats * 100% = 66.666...%, which rounds up to 67%. The answer is 67.
Q: Martha spends 10 minutes turning the router off and on again, six times that long on hold with Comcast, and half as much time as she spent on hold yelling at a customer service representative. How much time did Martha spend on these activities total?
A: First find the total time Martha spent on hold: 10 minutes * 6 = 60 minutes. Then find the time she spent yelling: 60 minutes / 2 = 30 minutes. Then add all the amount of time to find the total time: 60 minutes + 30 minutes + 10 minutes = 100 minutes. The answer is 100.
Question: A special balloon increases by two-fifths of its previous volume every hour when placed under water. If its original volume is 500cm³, what will its volume be after 2 hours underwater?
Answer: In the first hour, the balloon will increase in volume by two - fifths of 500cm³ which is (2 / 5) * 500cm³ = 200cm³. After the first hour, it will have a volume of (500 + 200)cm³ = 700cm³. In the second hour, it will increase in volume by two - fifths of 700cm³ which is (2 / 5) * 700cm³ = 280cm³. After the second hour, it's volume will be (700 + 280)cm³ = 980cm³. The answer is 980.
[Question]The total mask production was doubled every month by a company after the outbreak of Coronavirus due to increased demand. If the company produced 3000 masks in March, calculate the total mask production of July.
[Answer]If in March the company produced 3000 masks, in April, after doubling the total mask production, the company produced 3000 * 2 = 6000 masks. In May, the company doubled its total mask production to 2 * 6000 = 12000. After doubling the production for June, the company was able to produce 2 * 12000 = 24000. By July, the company was producing a total of 2 * 24000 = 48000 masks. The answer is 48000.
Q: Moses and Tiffany want to see who is faster. But instead of a race, they just start running down the block. Tiffany runs 6 blocks in 3 minutes. Moses runs 12 blocks in 8 minutes. What is the speed (defined as blocks per minute) of the runner with the higher average speed?
A: Tiffany runs 2 blocks per minute because 6 / 3 = 2. Moses runs 1.5 blocks per minute because 12 / 8 = 1.5. The runner with the highest average speed is Tiffany because 2 > 1.5. The answer is 2.
Question: Zach was a waiter in a fancy restaurant. His last table for the night was a party for 4 people. The mom ordered lobster for $25.50, the dad ordered steak for $35.00 their twin boys both ordered a cheeseburger and fries for $13.50 each. They started their meal with an appetizer that cost 8.50. Everyone also ordered a dessert that cost $6.00 each. They wanted to give a 20% tip for Zach on the bill. What did the final bill total come to?
Answer:
The twins ordered a cheeseburger each so 2 * 13.50 = $27.00 for both cheeseburgers. Everyone ordered a dessert so 4 * 6 = $24.00 for dessert. When you add all the meals together they spent 25.50 + 35.00 + 27.00 + 8.50 + 24.00 = $120.00. Zach's tip was 20% so .20 * 120.00 = $24.00. When you add up the meals $120.00 and Zach's tip of $24.00 then the total cost is 120.00 + 24.00 = $144.00. The answer is 144.
