A small airplane can seat 10 people in first class, 30 in business class, and 50 in economy class seating. If economy class is half full, and business class and first class have the same number of people together as economy class, how many seats are unoccupied in business class if only three people on the flight have first class seats?
Let's think: There are 50 / 2 = 25 people in economy class. There are 25 people in business first and business class, so there are 25 - 3 = 22 in business class. Thus, there are 30 - 22 = 8 unoccupied seats in business class.. The answer is: 8.

A watermelon weighs 23 pounds. If Farmer Kent sells his special watermelons for $2 a pound, how much money would he make for selling 18 watermelons of the same weight?
Let's think: A single watermelon would sell for $2 x 23 = $46. 60 watermelons would sell for $46 x 18 = $828.. The answer is: 828.

At a recent fishing tournament, Alex caught 7 times as many fish as Jacob. Jacob did not think that he had any chance of winning, but Alex became overconfident and knocked over his bucket of fish, losing 23 fish back to the lake. If Jacob had 8 fish at the beginning, how many more fish does he need to catch to beat Alex by just 1 fish?
Let's think: At the beginning, Jacob had 8 fish. Alex had 7 * 8 = 56 fish. After knocking the bucket over, Alex was left with 56 - 23 = 33 fish left. The final amount caught by Jacob to beat Alex by 1 fish is 33 + 1 = 34 fish. Then Jacob needs to catch 34 - 8 = 26 fish more.. The answer is: 26.

Janet goes to the gym for 5 hours a week. She goes Monday, Tuesday, Wednesday, and Friday. She spends an hour and a half each day on Monday and Wednesday. If she spends the same amount of time at the gym on Tuesday and Friday how many hours is she at the gym on Friday?
Let's think:
Between Monday and Wednesday, she spends 1.5 hours + 1.5 hours = 3 hours. That means she has 5 hours - 3 hours = 2 hours left for Tuesday and Wednesday. She spends 2 hours / 2 = 1 hour on Friday.. The answer is: 1.
