First of all, we can eliminate choices B and D because subtraction will not help us find the sister's age. 

Since Abbie is 5 years older than twice her sister's age, we can multiply to figure out her sister's age. To form the equation, letter C would be your best choice.

Hope that helps. -UnicornFudge aka Nadia
