\dfrac{2x-3}x = \dfrac{14}{x+5}\\\\\implies (2x-3)(x+5) = 14x\\\\\implies 2x^2 +10x -3x -15 -14x=0\\\\\implies 2x^2-7x-15=0\\\\\text{Apply quadratic formula,}~~x= \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}.\\\\\text{In this case,}~ a=2, b=-7~ \text{and}~ c = -15. \\\\\\x = \dfrac{-(-7) \pm \sqrt{(-7)^2 -4\cdot 2 \cdot (-15)}}{2(2)}\\\\\\\implies x = \dfrac{7 \pm \sqrt{169}}{4}\\\\\\\implies x = \dfrac{7 \pm 13}4\\\\\\

\text{Hence} ~x = \dfrac{7+13}{4} = \dfrac{20}4 = 5 ~\text{or}~ x = \dfrac{7-13}4 = -\dfrac{6}4 = -\dfrac 32

An insured has $5,000 of medical coverage on a personal auto policy at the time of a covered accident. The insured and two passe
Vlad1618 [11]

Answer: 14,000 $ Max will be paid and 5000$ per person.

Step-by-step explanation:

In this case, we can assume the following:

1. That the policy covers only the insured one and not the passengers

2. The policy cover all the injured.

Now, the policy covers 5000$ of medical treatment, so, the medical treatment for the insured is 7000$.

To this quantity you'll have to take out the policy coverage which is 5000$, so: 7000 - 5000 = 2000$.

Finally, we just have to to the sum, of all quantity, because the passengers are not included in the policy, therefore:

8000 + 4000 + 2000 = 14000 $.

That is the maximum paid of all, and 5000$ will pay the policy for the injured only.

Now, if we assume that the passengers are also covered by the policy, then:

7000 - 5000 = 2000

8000 - 5000 = 3000

4000 - 5000 = -1000 it won t pay anything.

So if we sum 5000 + 5000 + 4000 = 14000$.

We got the same result assuming the policy with all.

Therefore the final answer is that the policy will pay 14000$ for all.
