Question: Samantha’s last name has three fewer letters than Bobbie’s last name. If Bobbie took two letters off her last name, she would have a last name twice the length of Jamie’s. Jamie’s full name is Jamie Grey. How many letters are in Samantha’s last name?
Answer with step-by-step thinking: There are 4 letters in Jamie’s last name, so Bobbie’s name is 4 * 2 + 2 = 10 letters long. Samantha’s last name is 3 letters shorter than Bobbie’s, so there are 10 - 3 = 7 letters in Samantha’s last name.
So the answer is 7.


Question: Maiya has two sisters. The first sister is twice as old as Maiya. The first sister is 1 year younger than Maiya. Their average age is 5. How old is Maiya?
Answer with step-by-step thinking:
Their total age is 15 because 3 x 5 = 15. 15 - X - 2X - (X - 1) is equivalent to 16 = 4X. Maiya is 4 years old because 16 / 4 = 4.
So the answer is 4.
