Answer : She will hike about 18 kilometers in 6 hours .
Explanation :
Since we have given that
on every 4 hours , she hikes about 12 kilometers
![\text{on every 1 hour, she hikes about }\frac{12}{4}\text{ kilometers}](https://tex.z-dn.net/?f=%5Ctext%7Bon%20every%201%20hour%2C%20she%20hikes%20about%20%7D%5Cfrac%7B12%7D%7B4%7D%5Ctext%7B%20kilometers%7D)
![i.e. 3\text{ kilometers}](https://tex.z-dn.net/?f=i.e.%203%5Ctext%7B%20kilometers%7D)
![\text{So , every 6 hours, she hikes about =}6\times 3\text{kilometers}=18\texr{ kilometers](https://tex.z-dn.net/?f=%5Ctext%7BSo%20%2C%20every%206%20hours%2C%20she%20hikes%20about%20%3D%7D6%5Ctimes%203%5Ctext%7Bkilometers%7D%3D18%5Ctexr%7B%20kilometers)
Hence, she will hike about 18 kilometers in 6 hours .
If the pool's being filled at a constant rate, then this rate is equal to the average rate, which would be
(2352 gal - 1372 gal) / (12 min - 7 min) = 980/5 gal/min = 196 gal/min
<u>When we say to </u><u><em>solve for something</em></u>
<em> ⇒ essentially move everything to one side</em>
<em> ⇒ and that 'something' to the other</em>
<em />
In this case:
⇒ we need to move the y-variable by itself to one side
⇒ and everything else to the other
<em />
<u>Let's apply that principle</u>:
![12y+d=-19y+t\\12y+19y=t-d\\31y=t-d\\y=\frac{t-d}{31}](https://tex.z-dn.net/?f=12y%2Bd%3D-19y%2Bt%5C%5C12y%2B19y%3Dt-d%5C%5C31y%3Dt-d%5C%5Cy%3D%5Cfrac%7Bt-d%7D%7B31%7D)
<u>Answer: (t-d) / 31</u>

(26 x 1334) + (19 x 749)
This would equal 34684 + 14231 or 48915
$48915 is how much it costs.
Hope this helps :)
