For each babysitting job, Tamar charges $6 for bus fare plus $8 per hour. She only accepts babysitting jobs if the total charge is at least $30. What is the minimum number of hours for a babysitting job she would accept? 2 and one-half hours
3 hours
4 hours
4 and one-half hours

3 hours

Step-by-step explanation:

Let Tamar did the job for x hours,

Since, her charges for 1 hour = $ 8,

⇒  Her charge for x hours = 8x,

Also, the bus fare = $ 6,

hence, her total charge = Bus fare + Her charges for x hours

= 6 + 8x,

If the total charge is at least $30,

⇒ 6 + 8x ≥ 30

⇒ 8x ≥ 24

⇒ x ≥ 3

Thus, the minimum number of hours for a babysitting job she would accept = 3 hours

Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?

i used to know but i learned it a long time ago sorry

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
