Question: Elida has 5 letters while Adrianna has 2 less than twice the number of letters Elida has. What's 10 times the average number of letters in both names?
Answer: Twice the number of letters Elida has is 2 * 5 = 10. 2 less than twice the number of letters Elida has is 10 - 2 = 8. The total number of letter in both names is 8 + 5 = 13. The average number of letters in the name Elida and Adrianna is 13 / 2 = 6.5. 10 times the average number of letters in both names is 10 * 6.5 = 65. The answer is 65.
