C. She is not correct. The correct answer is 24.

D. She is not correct. The correct answer is 26.

Answer 1

C. She is not correct. The correct answer is 24.

To simplify the expression, we follow the order of operations (PEMDAS):

First, we evaluate the parentheses:

(27-9) = 18

Next, we perform the multiplication and division (from left to right):

18 × 3 ÷ 9 = 6

Finally, we perform the addition and subtraction (from left to right):

6 + 18 = 24

Therefore, Phillipa's answer is not correct.
