[Question]Buying a toaster requires an insurance plan that is 20% of the MSRP, plus a mandatory state tax rate of 50% after the insurance plan calculation. Jon chooses to buy a toaster that costs $30 at MSRP. What is the total he must pay?
[Answer]The insurance plan costs $30 * 0.2 = $6. The pre - state tax total is $30 + $6 = $36. State tax will be $36 * 0.5 = $18. Jon needs to pay $18 + $36 = $54 for his new toaster. The answer is 54.
Q: Mariel is a dog walker. While walking her pack of dogs, she gets tangled up in the leashes of another dog walker and their 3 dogs. There are 36 legs tangled up in leashes. How many dogs is Mariel walking?
A: There are 2 dog walkers and they each have 2 legs so that's 2 * 2 = 4 legs. The other dog walker is walking 3 dogs that each have 4 legs so that's 3 * 4 = 12 legs. The dog walkers have 4 legs and the other dogs have 12 legs for a total of 4 + 12 = 16 legs. There are 36 legs total and 16 belong to the dog walkers and 3 dogs so that leaves 36 - 16 = 20 legs. Dogs have 4 legs and there are 20 legs so Mariel is walking 20 / 4 = 5 dogs. The answer is 5.
Question: Cheryl is signing up for a golf tournament that costs 20% more than her monthly cell phone expenses to enter the tournament. If Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, which costs $800, calculate the total amount she pays upon signing up for the golf tournament.
Answer: If the electricity bill costs $800, and Cheryl spends $400 more on her monthly cell phone expenses than on the electricity bill, she pays $800 + $400 = $1200 on cell phone expenses. Since the cost to enter the tournament is 20% more than Cheryl's monthly cell phone expenses, to enter the tournament, Cheryl has to pay 20 / 100 * 1200 = $240 more than her monthly cell phone expenses. The total cost of joining the golf tournament is $1200 + $240 = $1440. The answer is 1440.
[Question]Before Cameron broke his right arm, he was able to type 10 words per minute on his phone. After he broke his arm, he had to use his left hand for a while, and he could only type 8 words per minute. What is the difference between the number of words he could type in 5 minutes before and after he broke his arm?
[Answer]Before Cameron broke his hand he could type 5 × 10 = 50 words in 5 minutes. After he broke his hand he could only type 5 × 8 = 40 words in 5 minutes. The difference between the number of words he could type in 5 minutes before and after he broke his arm is 50 - 40 = 10 words. The answer is 10.
Q: Dorothy, Julia, and Robert go to the store to buy school supplies. Dorothy buys half as many pens as Julia. Julia buys three times as many pens as Robert. Robert buys 4 pens. If one pen costs $1.50, how much money did the three friends spend in total on pens?
A: Julia buys 4 * 3 = 12 pens. Dorothy buys 12 / 2 = 6 pens. The total number of pens purchased is 4 + 12 + 6 = 22 pens. The total cost of the pens is 22 * $1.50 = $33. The answer is 33.
Question: Jackson wants to impress his girlfriend by filling her hot tub with champagne. The hot tub holds 40 gallons of liquid. Each bottle of champagne holds 1 quart. (There are 4 quarts per gallon). If each bottle of champagne costs $50, but Jackson gets a 20% volume discount, how much does he spend on champagne?
Answer:
First find the number of quarts the hot tub holds by multiplying the number of gallons it holds by 4: 40 gallons * 4 quarts / gallon = 160 quarts. Then multiply the number of quarts of champagne Jackson buy by the normal price per bottle to find the cost before the discount: 160 quarts * $50 / quart = $8000. Then multiply that number by 20% to find the amount of the discount: $8000 * .2 = $1600. Finally, subtract the discount from the total cost to find the final amount Jackson pays: $8000 - $1600 = $6400. The answer is 6400.
