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: A dime has the same value as 10 pennies and a nickel has the same value as 5 pennies. How many pennies will Grace have by exchanging her 10 dimes and 10 nickels?

Q: Charley bought 30 pencils. She lost 6 pencils while moving to school, and of course, also lost 1/3 of the remaining pencils because she wasn't very good at keeping track of pencils. How many pencils does she currently have?
A:
If Charley bought 30 pencils and lost 6 while moving, she remained with 30 - 6 = 24 pencils. Because she isn't good at keeping track of her pencils, Charley lost 1 / 3 * 24 = 8 more pencils. She currently has 24 - 8 = 16 pencils. The answer is 16.
