Answer:
To represent Sheila's age next year, we need to consider the information given in the question. It states that next year, Sheila's age will be twice what her sister's age is now. Let's break down the problem and solve it step by step.
Let's assume that Sheila's current age is S, and her sister's current age is A. We are asked to find an expression that represents Sheila's age next year.
According to the given information, next year Sheila's age will be twice her sister's current age. So, we can write the equation as:
Sheila's age next year = 2 * (Her sister's current age)
Since we don't know her sister's current age, we will use the variable A to represent it. Therefore, the expression representing Sheila's age next year can be written as:
Sheila's age next year = 2A
This expression represents Sheila's age next year based on the given information.
In summary, the expression that represents Sheila's age next year is 2A.
