Answer 2

The correct phrasing for your sentence would be:

"If Sarah didn't earn enough money, she wouldn't travel abroad."

In this conditional sentence, you are talking about a hypothetical situation (Sarah not earning enough money) and its consequence (her not traveling abroad). Therefore, you should use the past tense "wouldn't" to indicate the hypothetical outcome.
