Q: Madison takes her dog to the dog park. Counting Madison's dog, half the dogs have spots and 1/5 have pointy ears. If 15 dogs have spots, how many have pointy ears?
A: First double the number of dogs with spots to find the total number of dogs: 15 dogs * 2 = 30 dogs. Then multiply that number by 1 / 5 to find the number that have pointy ears: 30 dogs * 1 / 5 = 6 dogs. The answer is 6.

Q: Harvey and his friend Sam decided to run a footrace in their school track field to see who was better at running. While at it, Harvey runs 8 miles more than his friend Sam, who runs a total of 12 miles. Calculate the total number of miles the two friends run together.
A: If Harvey ran 8 more miles, then he ran a total of 12 miles + 8 miles = 20 miles. The two friends ran a total of 20 miles + 12 miles = 32 miles. The answer is 32.

Q: A shopping center sells T-shirts at $8 each, a sweater at $18, and a jacket at $80. The jacket is on sale with a 10% discount. The sales tax is 5%. Kevin wants to buy six T-shirts, four sweaters, and five jackets for his children. How much does Kevin have to pay for all the items, including the sales tax?
A:
The six T - shirts cost 6 x $8 = $48. The four sweaters cost 4 x $18 = $72. And five jackets normally cost 5 x $80 = $400. So, a discount of 10 / 100 x $400 = $40 for the five jackets. Thus, the selling price of the five jackets is $400 - $40 = $360. Hence, the total cost of all the items is $48 + $72 + $360 = $480. The sales tax is equal to 5 / 100 x $480 = $24. Therefore, Kevin has to pay $480 + $24 = $504. including the sales tax. The answer is 504.
