Answer: The mountain paths were dangerous and couldn't guarantee a safe travel- for example, mountain lions are a true fact. Also, the climate and weather conditions in mountains were too risky, so they had to go around them

Answer:

Mileage = $71

Loading/Unloading Fee: -$980

Explanation:

The question has incomplete details. The complete question can be found online. The given parameters are:

Situation A

$Helpers = 6$

$Distance =95$

$Cost = 865$

Situation B

$Helpers = 5$

$Distance = 80$

$Cost = 780$

Solving (a): The equation.

Let

<em>x = loading/unloading fee</em>

<em>y = mileage fee</em>

For situation A, the equation will be:

$Cost = 6 * x + 95 * y$

$Cost = 6 x + 95y$

$6 x + 95y = 865$

For situation B, the equation will be:

$Cost = 5* x + 80*y$

$Cost = 5x + 80y$

$5x + 80y = 780$

So, the equations are:

$6 x + 95y = 865$

$5x + 80y = 780$

Solving (b): The solution

$6 x + 95y = 865$ --- (1)

$5x + 80y = 780$ --- (2)

Multiply (1) by 5 and multiply (2) by 6 to eliminate x

$5 * [$ $6 x + 95y = 865$ $]$

$30x + 475y = 4325$

$6*[$ $5x + 80y = 780$ $]$

$30x + 480y = 4680$

Subtract the resulting equations

$30x - 30x + 475y - 480y = 4325 - 4680$

$-5y = -355$

Divide both sides by -5

$y = 71$

Substitute $y = 71$ in (1)

$6 x + 95y = 865$

$6x + 95 * 71 = 865$

$6x + 6745 = 865$

Collect like terms

$6x =- 6745 + 865$

$6x =-5880$

Divide both sides by 6

$x =-980$

<em>The solution is correct but does not represent real life situation because x should be positive</em>
