Write as an equation: After withdrawing $7 from a checking account, Carla's balance was $89.

A. \( w - 7 = 89 \)

B. \( 7 - w = 89 \)

C. \( w + 89 = 7 \)

D. \( w = 89 - 7 \)

Answer :

Answer:

A. w - 7 = 89

Explanation:

I think it's w - 7 = 89 because there is a key word in the question and that key word is withdraw. If you withdraw something then that means that it's subtraction. You don't know how much Carla's bank balance was before withdrawing so it's a variable (w). Therefore it's w - 7 = 89.
