Option D is the correct answer.

Explanation:

As given, if the car is returned with a fuel level below the mentioned level, it will be completely re-fueled and the cost will be added to Tim's total bill.

As, the fuel needed to fill the car is 11.75 gallons and cost of a gallon is $4.50, so total cost becomes

= $11.75\times4.50=52.875$

And the cost of re fueling is $5, so total cost becomes = $52.875+5=57.875$ ≈ $57.88

So, total cost is $57.88 (option D)

Answer:

b. $31.44

Step-by-step explanation:

The tank holds 11.75 gallons. Tim will need to get half of this amount to bring the tank back up to half full; this is

11.75/2 = 5.875

The gas costs $4.50 per gallon; this means the cost is

5.875(4.50) = 26.4375 ≈ 26.44.

There is also a $5 refueling charge; this makes the total cost

26.44+5 = 31.44

Which of the below descriptions shows a possible HAMILTON PATH?

Option B: FECBAD represents the Hamilton path

Explanation:

The vertices in the given graph are A,B,C,D,E and F

We need to determine the Hamilton path of the given graph.

By definition, we know that a Hamilton path touches each and every vertex in a graph exactly once.

Hence, we need to connect the vertices in such a way that the graph touches each and every vertex exactly once.

Option A: EFADECBA

From this description, we can see that the path starts from the vertex E and connects all the vertices but some of the vertices are repeated twice.

Hence, the path EFADECBA is not a Hamilton path.

Therefore, Option A is not the correct answer.

Option B: FECBAD

From this description, we can see that the path starts from the vertex F and connects all the vertices exactly once.

Hence, the path FECBAD is the Hamilton path.

Therefore, Option B is the correct answer.

Option C: ADEFBC

From this description, we can see that the path starts from the vertex A and connects all the vertices but the path from F to B has to touch the vertex A. Thus, the vertices are repeated twice.

Hence, the path ADEFBC is not a Hamilton path.

Therefore, Option C is not the correct answer.

Option D: ADECBAFE

From this description, we can see that the path starts from the vertex A and connects all the vertices but some of the vertices are repeated twice.

Hence, the path ADECBAFE is not a Hamilton path.

Therefore, Option D is not the correct answer.
