Question

Josefina originally had $550 in her checking account. After withdrawing $100 each week, Josefina has a new balance of $50. Which best represents w, the number of weeks Josefina withdrew money from her checking account?

A. 550 - 100w = 50

B. 550 + 100w = 50

C. 50 + 100w = 550

D. 50 - 100w = 550

Answer 1

Answer: A

Reasoning: she started out with 550 dollars and takes 100 each week. So you would multiple the 100 by the number of weeks. You would need to then subtract the original amount by the amount getting taken away to then equal the 50 dollars.
I hope that made sense
