When planning a more strenuous hike, Erin figures that she will need at least 0.8 liters of water for each hour on the trail. She also plans to always
have at least 1.50 liters of water as a general reserve. If x represents the
duration of the hike (in hours) and y represents the amount of water needed
(in liters) for a hike, the following inequality describes this relation:
y 20.8x + 1.5
Which of the following would be a solution to this situation?

step-by-step explanation:

i am not sure sorry : c

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
