Lena needs $50 to buy some notebooks. She had saved $2 and plans to work as a babysitter to earn $8 per hour. Which inequality shows the minimum number of hours, n, that Lena should work as a babysitter to earn enough to buy the notebooks?

2 + 8n ≤ 50, so n ≤ 6
8n ≤ 50 + 2, so n ≤ 6.5
8n ≥ 50 + 2, so n ≥ 6.5
2 + 8n ≥ 50, so n ≥ 6
