WILL GIVE ANYTHING I NEED HELP!!!

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 last option

Answer 2

Nina needs at least 50$ to buy her books so you know that the inequality must be greater than or equal to 50 at least

Answer 3

so last one u said?

Answer 4

Do you agree because i have hard questions?

Answer 5

She starts with 2 dollars so this number will be a constant added to the changing quantity ( time babysat multplied by the amount earned)

Answer 6

It's the last one because in the first one, it says she has to make less than or equal to 50 but you know she needs $50 so there's no way she can get less than 50

Answer 7

Answer 8
