Olivia needs $36 to buy a coat. she has saved $8 and plans to work as a babysitter to earn $7 per hour. which inequality shows the minimum number of hours, n, that olivia should work as a babysitter to earn enough to buy the coat? (5 points) 7n ≥ 36 + 8, so n ≥ 6.3 8 + 7n ≤ 36, so n ≤ 4 7n ≤ 36 + 8, so n ≤ 6.3 8 + 7n ≥ 36, so n ≥ 4

The last inequality will work because if n is equal to four, then she will earn $28 in total (7*$4=$28). Add that to the $8 that she saved and you get $36, just enough for the coat she wants to buy.

I think the answer could be 8 + 7n ≥ 36, so n ≥ 4, but I am not certain...

Step-by-step explanation:

Hope this can help! :)

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
