Answer:
The price elasticity of demand is -10
Step-by-step explanation:
Given


Solving (a): The coefficient of price elasticity of demand (k)
This is calculated as:

So, we have:



<em>Because |k| > 0, then we can conclude that the company made a wise decision.</em>
First ne is 3x then 2x then 26x
C because for every mile the cost increases be $4.75
Answer:
We know that the rectangular plate has measures of:
length = 7.6 ± 0.05 cm
width = 3.1 ± 0.05 cm
(the error is 0.05cm because we know that both measures are correct to one decimal place)
First, the upper bound of the length is equal to the measure of the length plus the error, this is:
L = 7.6 cm + 0.05 cm = 7.65 cm
The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.
Remember that the area for a rectangle of length L and width W, is:
A = W*L
Then the upper bound of the area is:
A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
