Answer:
$324
Step-by-step explanation:
We need to make a proportion:
![\frac{259.20}{x} = \frac{80}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B259.20%7D%7Bx%7D%20%20%3D%20%20%5Cfrac%7B80%7D%7B100%7D%20)
![25920 = 80x](https://tex.z-dn.net/?f=25920%20%3D%2080x)
![x = 324](https://tex.z-dn.net/?f=x%20%3D%20324)
x is 1%. So 100% = 324*100 = 32400 cents = $324

Step-by-step explanation:
The shortest length needed to connect the house to the existing pipeline is the perpendicular distance between the location of the house (2,9) and the line y = 2/3x - 1.
The perpendicular distance (d) between a point (
) and the line Ax + By + C = 0 is given as:
![d=\frac{|Ax_1+By_1+C|}{\sqrt{A^2+B^2} }](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B%7CAx_1%2BBy_1%2BC%7C%7D%7B%5Csqrt%7BA%5E2%2BB%5E2%7D%20%7D)
The line is given by y = 2/3 x - 1; 2/3x - y - 1 = 0. The point = (2, 9)
hence A = 2/3, B = -1, C = -1,
. Therefore:
![d=\frac{|\frac{2}{3}(2)+(-1)(9)+(-1) |}{\sqrt{\frac{2}{3}^2+(-1)^2 } } \\\\d=7.21](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B%7C%5Cfrac%7B2%7D%7B3%7D%282%29%2B%28-1%29%289%29%2B%28-1%29%20%7C%7D%7B%5Csqrt%7B%5Cfrac%7B2%7D%7B3%7D%5E2%2B%28-1%29%5E2%20%7D%20%7D%20%5C%5C%5C%5Cd%3D7.21)
247 / 13 = 323 / x....247 to 13 hrs = 323 to x hrs
cross multiply
(247)(x) = (323)(13)
247x = 4199
x = 4199 / 247
x = 17 hrs <===
