[Question]: Tyler has $100. If he buys 8 scissors for $5 each and 10 erasers for $4 each, how much of his money remains?
[Answer]: 8 * $5 = $40 is the price of 8 scissors. 10 * $4 = $40 is the price of 10 erasers. You can find the total price by adding the cost of the scissors and erasers: $40 + $40 = $80. $100 - $80 = $20 is the remaining amount of his money.
So the answer is 20.

[Question]: From Sunday to Thursday, Prudence sleeps 6 hours a night. Friday and Saturday she sleeps for 9 hours a night. She also takes a 1-hour nap on Saturday and Sunday. How much sleep does she get in 4 weeks?
[Answer]: 5 nights a week she sleeps for 6 hours so she sleeps 5 * 6 = 30 hours. 2 nights a week she sleeps for 9 hours so she sleeps 2 * 9 = 18 hours. 2 days a week she naps for 1 hour so she sleeps 2 * 1 = 2 hours. Over 1 week she sleeps 30 + 18 + 2 = 50 hours. Over 4 weeks she sleeps 4 * 50 = 200 hours.
So the answer is 200.

[Question]: Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm?
[Answer]:
Twice the number of pigs is 10 x 2 = 20. So, Hannah's family has 20 - 3 = 17 cows. They also have 17 + 6 = 23 goats. So, they have a total of 10 + 17 + 23 = 50 animals on their farm.
So the answer is 50.
