Three years older than twice his brother's age.
To find the algebraic expression that represents Dane's age, we need to analyze the given information.
We know that Dane is three years older than twice his brother's age, 'b'.
Twice his brother's age is represented by the expression 2b.
Since Dane is three years older than this, we add 3 to the expression 2b.
Therefore, the correct algebraic expression that represents Dane's age is 2b + 3.
So, the answer is B.
