Each time he withdraws x dollars and pays a $2 fee.
That means that each time he withdraws x + 2 dollars from his account.
He did it 7 times, so the total amount he withdrew was 7(x + 2).
7(x + 2) = 7x + 14
Now look at each choice and see which ones are equal to 7x + 14.
A. 7x + 9 <--- not equal
B. (7)(x) + (7)(2) = 7x + 14 <---- equal
C. (7)(x) + (7)(2x) = 7x + 14x = 21x <--- not equal
D. 7(x + 2) = 7x + 14 <--- equal
E. 7x + 14 <---equal
F. 7x + 2 <--- not equal
Answer: Choices B, D, and E correct.
