Q: At a UFO convention, there are 120 conference attendees. If there are 4 more male attendees than female attendees, how many male attendees are there?
A: Let's assume the number of female attendees is x. The number of male attendees is x + 4. The sum of male attendees and female attendees is x + x + 4 = 120. 2x + 4 = 120. 2x = 116. The number of female attendees is x = 116 / 2 = 58. The number of male attendees is 58 + 4 = 62. The answer is 62.
Question: The number of math problems that Marvin practiced today is three times as many as the number of problems he solved yesterday. His friend, Arvin, has practiced twice as many math problems on each day. How many math problems have they practiced altogether if Marvin solved 40 math problems yesterday?
Answer: If Marvin solved 40 math problems yesterday, he has solved 40 * 3 = 120 math problems today. The total number of math problems that Marvin has practiced is 120 + 40 = 160. Arvin has practiced twice as many as Marvin, so has practiced 160 * 2 = 320 problems. Together, Marvin and Arvin have solved 320 + 160 = 480 math problems. The answer is 480.

Question: The price per organic egg is 50 cents. The price of a tray of eggs that contains 30 eggs is $12. How much can you save, in cents, per egg if you buy a tray versus individual eggs?
Answer:
The price per egg in a tray is $12 / 30 eggs = $0.4 / egg. The equivalent of $0.4 in cents is $0.4 x 100 cents / dollar = 40 cents. Hence, you can save 50 cents - 40 cents = 10 cents per egg if you buy a tray. The answer is 10.
