Question: A gallon of whole milk that normally costs $3 is now sold at $2. A box of cereal was sold at a discount of $1. How much will you save via discounts if you buy 3 gallons of whole milk and 5 boxes of cereal?
Answer: The discount for each gallon of whole milk is $3 - $2 = $1. So the discount for 3 gallons of whole milk is $1 / gallon x 3 gallons = $3. The total discount for 5 boxes of cereal is $1 / box x 5 boxes = $5. You will save $3 + $5 = $8 for 3 gallons of whole milk and 5 boxes of cereal. The answer is 8.
[Question]Sammy can eat 15 pickle slices. His twin sister Tammy can eat twice as much as Sammy. Their older brother Ron eats 20% fewer pickles slices than Tammy. How many pickle slices does Ron eat?
[Answer]Tammy can eat twice as many pickle slices as Sammy who eats 15 so Tammy can eat 15 * 2 = 30 pickle slices. Ron eats 20% fewer pickle slices than Tammy who eats 30 pickle slices so that's .20 * 30 = 6 fewer slices than Tammy. Tammy eats 30 slices and Ron eats 6 less, then Ron eats 30 - 6 = 24 pickle slices. The answer is 24.
Q: Harry owns 3 geckos, 2 iguanas, and 4 snakes. If he spends $10 to feed each snake, $5 to feed each iguana, and $15 to feed each gecko every month, how much does he spend every year to feed all his pets?
A: He spends $10 / snake * 4 snakes = $40 to feed his snakes every month. He spends $5 / iguana * 2 iguanas = $10 to feed his iguanas every month. He spends $15 / gecko * 3 geckos = $45 to feed his geckos every month. So overall he spends $40 + $10 + $45 = $95 to feed all his pets every month. Therefore every year pet food costs him $95 / month * 12 months = $1140. The answer is 1140.

[Question]A snake's head is one-tenth its length. If a snake is 10 feet long, calculate the length of the rest of its body minus the head.
[Answer]
A snake's head is one - tenth its length, which is 1 / 10 * 10 = 1 foot. Since the snake's head is 1 foot, the rest of its body is 10 - 1 = 9 feet long. The answer is 9.
