Susan makes $5 per hour babysitting and $7 per hour as a lifeguard. Her goal is to make at least $140. Which of the following represents three possible solutions to the problem?

Here is the answer. Given that Susan makes $5 per hour in babysitting and $7 per hour as a lifeguard and her goal is to make at least $140, the equation that would best represent three possible solutions to the problem is this: 5x + 7y ≥ 140. Hope this answers your question.
