.
Is she correct? If not, what is the correct answer?

C.
She is not correct. The correct answer is 24.
D.
She is not correct. The correct answer is 26.
C. She is not correct. The correct answer is 24.
(27 - 9) = 18
18 × 3 = 54
54 ÷ 9 = 6
6 + 18 = 24
To determine if Phillipa's calculation is correct, let's break it down step-by-step and compare it to the given expression:
1. Evaluate (27 - 9) = 18.
2. Multiply 18 by 3, which gives us 54.
3. Divide 54 by 9, resulting in 6.
4. Add 6 to 18, giving us the final answer of 24.
Therefore, the correct answer is 24.
So, the correct option is C. She is not correct. The correct answer is 24.
