[Question]Jack is counting out his register at the end of his shift in the shop. His till has 2 $100 bills, 1 $50 bill, 5 $20 bills, 3 $10 bills, 7 $5 bills, 27 $1 bills, and a certain amount of change in coins. If he is supposed to leave $300 in notes as well as all the coins in the till and turn the rest in to the main office, how much money will he be handing in?
[Answer]Jack's till has 2 * $100 + 1 * $50 + 5 * $20 + 3 * $10 + 7 * $5 + 27 * $1 bills, or $200 + $50 + $100 + $30 + $35 + $27 = $442. He's going to leave $300 in the till and turn the rest in to the office, so he'll be turning in $442 - $300 = $142. The answer is 142.
Q: Jill bought 5 packs of red bouncy balls and 4 packs of yellow bouncy balls. Each package contained 18 bouncy balls. How many more red bouncy balls than yellow bouncy balls did Jill buy?
A: Jill bought 5 packs * 18 red balls = 90 red balls. Jill bought 4 packs * 18 yellow balls = 72 red balls. Jill had 90 red – 72 yellow = 18 more red balls. The answer is 18.
Question: Jack cycles from his home to the store. Then he cycles, at the same speed, 50 miles to his friend Peter. It takes Jack twice as long to go from his home to the store as it takes to go from the store to his friend. If Peter and Jack now cycle back to the store together, how many miles in total have they cycled today?
Answer: When Jack cycles from home to the store, it takes 2 * 50 = 100 miles. He then cycles 50 miles to Peter. When Peter and Jack cycle back to the store, they cover a total of 50 + 50 = 100 miles. The total number of miles covered is 100 + 50 + 100 = 250 miles. The answer is 250.
[Question]Lee had $10 and his friend had $8. They went to a restaurant where they ordered chicken wings for $6 and a chicken salad for $4. They also got 2 sodas for $1.00 each. The tax came to $3. How much change should they have received in total?
[Answer]Lee and his friend had a total of $10 + $8 = $18. The cost of the food was $6 + $4 + $1 + $1 = $12. The total cost, including tax was $12 + $3 = $15. They should have received $18 - $15 = $3 in total. The answer is 3.
Q: There were 20 fishermen in the lake who had cast their net to catch fish. If they caught 10000 fish in total, and 19 of them caught 400 fish each with their own net, calculate the number of fish the twentieth fisherman caught.
A: The 19 fishermen who caught 400 fish each caught 400 * 19 = 7600 fish. If they caught a total of 10000 fish, the twentieth fisherman caught 10000 - 7600 = 2400 fish alone. The answer is 2400.

Sarah uses 1 + 0.5 = 1.5 ounces of hair care products daily. Two weeks is 2 * 7 = 14 days. In 14 days, Sarah will use 14 * 1.5 = 21 ounces of hair care products. The answer is 21.
