Let's address each part of your question step by step.
### A) Fill out the table
The total amount of food is 360 pounds, and they eat 12 pounds per day. The relationship between the number of days \( x \) and the amount of food left \( y \) can be described by the equation:
\[
y = 360 - 12x
\]
Now we can fill out the table for \( x = 0, 5, 10, 15 \):
1. For \( x = 0 \):
\[
y = 360 - 12(0) = 360
\]
2. For \( x = 5 \):
\[
y = 360 - 12(5) = 360 - 60 = 300
\]
3. For \( x = 10 \):
\[
y = 360 - 12(10) = 360 - 120 = 240
\]
4. For \( x = 15 \):
\[
y = 360 - 12(15) = 360 - 180 = 180
\]
So the completed table will look like this:
| x | y |
|-----|-------|
| 0 | 360 |
| 5 | 300 |
| 10 | 240 |
| 15 | 180 |
### B) Write the equation in slope-intercept form
The equation we've derived is already in slope-intercept form, \( y = mx + b \), where:
- \( m = -12 \) (the slope, representing the rate of food consumption per day),
- \( b = 360 \) (the y-intercept, representing the starting amount of food).
Thus, the equation in slope-intercept form is:
\[
y = -12x + 360
\]
### C) In how many days will the hikers run out of food?
To find out when the hikers will run out of food, we need to set \( y = 0 \) in the equation and solve for \( x \):
\[
0 = 360 - 12x
\]
Rearranging the equation:
\[
12x = 360
\]
Dividing both sides by 12:
\[
x = 30
\]
So the hikers will run out of food in 30 days.
**Summary:**
- **Table:** Completed above.
- **Equation:** \( y = -12x + 360 \)
- **Days until food runs out:** 30 days.
