Answer:
$10
Step-by-step explanation:
Let's take this step by step. First, we know that Cindy has -$40 in her bank account. She then adds the $100 she earned, so we add -40 and 100:
-40 + 100 is the same as 100 - 40, which is 60. So, Cindy now has $60 in her bank account. Next, she took out $50. We must subtract that from what she has from her bank account:
60 - 50 = 10
Therefore, Cindy has $10 in her bank account now.
Hope this helps :)
