Answer the following question.
While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all?
Step-by-step reasoning process: If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = 120 carriages. Together, Flying Scotsman and Norwich had 120 + 100 = 220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = 110 carriages. Together, Euston and Norfolk had 110 + 130 = 240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = 460 carriages.
The answer is 460.

Answer the following question.
In Hawaii, they normally get an average of 2 inches of rain a day. With 100 days left in the year, they've gotten 430 inches of rain. How many inches on average do they need to finish the year with the normal average?
Step-by-step reasoning process: They need 730 inches of rain a year to average 2 inches a day because 365 x 2 = 730. They need 300 more inches because 730 - 430 = 300. They need 3 inches a day because 300 / 100 = 3.
The answer is 3.

Answer the following question.
Jen buys and sells candy bars. She buys candy bars for 80 cents each and sells them for a dollar each. If she buys 50 candy bars and sells 48 of them, how much profit does she make in cents?
Step-by-step reasoning process: It costs Jen 80 * 50 = 4000 cents to buy 50 candy bars. Since a dollar is 100 cents, she earns 48 * 100 = 4800 cents by selling 48 of them. Thus her total profit is 4800 - 4000 = 800 cents.
The answer is 800.

Answer the following question.
An aqua park charges $12 admission and $6 for a tour. A group of 10 people goes to the aquarium and takes the tour; while a group of 5 people only goes to the aquarium. How much does the aqua park earn?
Step-by-step reasoning process: A group of 10 people is charged $12 + $6 = $18 each. So, 10 people pay $18 x 10 = $180. A group of 5 people pays $12 x 5 = $60 for the admission. Thus, the aqua park earns a total of $180 + $60 = $240.
The answer is 240.
