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: Alice was able to sell $2500 worth of gadgets. For this month, she expects to receive her monthly basic salary of $240 and a 2% commission from these sales. How much is she going to save this month if she usually saves 10% of her total earnings?
Answer: Alice will get $2500 x 2 / 100 = $50 from her commission. This month, she will receive a total of $240 + $50 = $290. Therefore, Alice will save $290 x 10 / 100 = $29 for this month. The answer is 29.

Q: Every year, Tabitha adds a new color to her hair. She started this tradition when she was 15 years old, which was the year she added her second hair color. In three years, Tabitha will have 8 different colors in the hair. Currently, how old is Tabitha?
A: Since, three years from now, Tabitha will have 8 different colors in her hair, this year she has 8 - 3 = 5 colors in her hair. Since she had 2 colors in her hair at the age of 15, she has added 5 - 2 = 3 colors since she was 15 years old. Since she ads one color per year, 3 added colors = 3 added years. Thus, currently, she is 15 + 3 = 18 years old. The answer is 18.
