Question. Beckett is 12 and is three years younger than Olaf, while Shannen is two years younger than Olaf. If Jack is five more than twice as old as Shannen, what is the sum of the ages of all 4 people?
Answer. 71
What step-by-step reasoning justifies that answer?
Reasoning: Olaf is 12 years + 3 years = 15 years old. Shannen is 15 years old - 2 years = 13 years old. Jack is 5 years + (2 * 13 years) = 31 years old. The sum of all of their ages is 12 + 15 + 13 + 31 = 71 years old.
