Answer this question:Lisa has 36 candies. On Mondays and Wednesdays, she eats 2 candies for each day and on the other days of the week she eats 1 candy for each day. How many weeks does it take for Lisa to eat all of the candies?
On Monday and Tuesday, she eats 2 * 2 = 4 candies. On the other days of the week, she eats 5 * 1 = 5 candies. In a week she eats 5 + 4 = 9 candies. So it takes 36 / 9 = 4 weeks for Lisa to eat all candies.
The answer is 4.

Answer this question:Andrea buys herself a pony for her 30th birthday. She pays $500/month to rent a pasture for it, $10 a day for food, and $60/lesson for two lessons a week. How much does she spend on her pony in a year?
First find the annual cost of food: $10 / day * 365 days = $3650. Then find how much she spends a week on lessons: $60 / lesson * 2 lessons = $120. Then multiply that weekly cost by the number of weeks per year to find the annual cost: $120 / week * 52 weeks / year = $6240. Then find the annual cost of the pasture: $500 / month * 12 months / year = $6000. Then add all the costs to find the total cost: $6000 + $6240 + $3650 = $15890.
The answer is 15890.

Answer this question:Marcus takes a deck of standard playing cards and takes out all the face cards and the 8's. Mark picks a card at random and then replaces it 36 times. How many times should he expect to pick a card that's both red and has a number divisible by 3?
Without the face cards and the 8's, there are 9 cards of each suit. Half these cards are red, and 3 / 9 have numbers divisible by 3, so the odds of drawing a card divisible by 3 are 1 / 3. Multiply the odds of drawing a red card by the odds of drawing a card divisible by 3 to find the odds of both things happening: 1 / 3 * 1 / 2 = 1 / 6. Finally, multiplying the probability of drawing a red / 3 - divisible card by the number of cards Mark draws to find how many he should expect to meet his criteria: 1 / 6 * 36 cards = 6 cards.
The answer is 6.

Answer this question:James needs 40 fish to make one sushi roll. He goes to the market and buys 400 fish, but later finds out that 20% of the fish have gone bad and cannot be used. How many sushi rolls did James make with the remaining fish?
If James bought 400 fish, the number of fish that were bad is 20 / 100 * 400 = 80. The remaining fish that he used to make the sushi rolls is 400 - 80 = 320. If 40 fish are required to make one sushi roll, 320 fish will make 320 / 40 = 8 sushi rolls.
The answer is 8.
