Question

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

Answer 1

The answer above is correct

Explanation:

I took the test and got a 100

Answer 2

Answer:2 + 8n ≥ 50

Explanation:

Total amount that Lena needed to buy the notebooks is $50

She had saved $2 and plans to work as a babysitter to earn $8 per hour. Let n represent the number hours that Lena should work. This means that the total amount that she can earn in n hours would be

8n + 2

The inequality that shows the minimum number of hours that Lena should work as a babysitter to earn enough to buy the notebooks would be

2 + 8n ≥ 50
