Answer:

The indifference point is 2.1 hours.

Step-by-step explanation:

<u>First, we need to calculate the total cost for each option:</u>

<u />

Dealership:

Total cost= 24 + 99x

Local mechanic:

Total cost= 45 + 89x

x= number of hours

<u>Now, we need to equal both formulas and isolate x:</u>

24 + 99x = 45 + 89x

10x = 21

x= 2.1

The indifference point is 2.1 hours.

<u>Prove:</u>

Total cost= 24 + 99*2.1= $231.9

Total cost= 45 + 89*2.1= $231.9

Hope this helps!

lisabon 2012 [21]

The average speed of Dolly is 33.33kmph.

Average Speed:

The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.

So, Average Speed = total distance / total time

Here,

Let the total distance is 100 km.

Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.

she will required times of 1 hour, 1hour and 1hour

So,

Average speed = 100 / (1 + 1 + 1)

=> 100 / 3 = 33.33

Tresset [83]

Answer:

1\frac{1}{3} cups of flour.

Step-by-step explanation:

Given that:

w is the number of cups of water to be mixed with flour for making tortillas.

f is the number of cups of flour to be mixed with water for making tortillas.

Relation between w and f is given by the equation:

w=0.75f

To find:

Number of cups of flour to be added if number of cups of water to be used is 1.

Solution:

We are given an equation with two variables.

Value of one variable is given and we have to find the value of other variable.

1=0.75f\\\Rightarrow f = \dfrac{1}{0.75}\\\Rightarrow f = 1.33

Number of cups of flour to be added = 1\frac{1}{3}
