Final answer:

To find when Christine will be three times as old as her daughter, use algebraic equations with Christine's age represented as C and her daughter's age as D. Plug in the values and solve for the unknown variable.

Explanation:

To solve this problem, let's use algebraic equations. Let's represent Christine's age as C and her daughter's age as D. In t years, Christine will be 3 times as old as her daughter, so the equation will be C + t = 3(D + t). Substitute C = 41 and D = 9 into the equation and solve for t.
