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

2 + 8n ≥ 50

Step-by-step 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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
