Answer:
46.2 mi is the right answer.
Step-by-step explanation:
In this question we will follow the property of congruence of two triangles.
Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.
The distance between Alba and Blare = 130 mi
The distance between Alba and Cray = 120 mi
As we know in the congruent triangles all sides are in the same ratio.
Now we apply the property of the theorem
![\frac{Distance(Alba-Cray)}{Distance(Alba-Blare)}= \frac{Distance(Cray-Service station)}{Distance(Cray-Blare)}](https://tex.z-dn.net/?f=%5Cfrac%7BDistance%28Alba-Cray%29%7D%7BDistance%28Alba-Blare%29%7D%3D%20%5Cfrac%7BDistance%28Cray-Service%20station%29%7D%7BDistance%28Cray-Blare%29%7D)
![\frac{120}{130}=\frac{x}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B120%7D%7B130%7D%3D%5Cfrac%7Bx%7D%7B50%7D)
![x=50\frac{120}{130}](https://tex.z-dn.net/?f=x%3D50%5Cfrac%7B120%7D%7B130%7D)
x = 46.2 mi
the answer would be 67,127 because the number in the ones would be 7 and the tens number would be 2 since it wouldn't more than 1.
67,102
67,135
1-7
67,127
(2·3.5 + 4·3.25 + 2·1.9 + 1·1.2)·(1 - 0.05) = $23.75
