If A is 2 times older than B, it means that A's age can be expressed in terms of B's age.
Let's assume B's age is \(x\). If A is 2 times older than B, this means A's age would be:
\[
A = B + 2B = 3B = 3x
\]
However, if the intention was to convey that A’s age is twice B’s age (which is a common misunderstanding with phrases like "2 times older"), then the equation would be:
\[
A = 2B = 2x
\]
Given the options:
- 0.2x (20% of x)
- 2% of x
- 2x
- 1.2x
With the explanation above, the most appropriate expression representing A's age, based on the interpretation that A is 2 times older than B, would be **2x**.
