Độ co giãn của cầu theo giá =-3 có nghĩa là gì

Mathematics
1 answer:
mario62 [17]3 years ago
6 0

Answer:

Step-by-step explanation:

What does price elasticity of demand = -3 mean ?

Price elasticity of demand = change in % of demand / change in % of price

So

change in % of demand / change in % of price = -3

or

change in % of demand = -3 * change in % of price

means that

when price is <em>increased</em> by 10 percent, the demand is <em>decreased</em> by 30 percent.

This happens when there is a possibility of substitution, such as coffee and tea.  When coffee prices are increased by 10%, the demand of coffee is decreased by 30%.

In arithmetic sequence the first term is 5 and the common difference is 4. Determine the 6th term of sequence
Harlamova29_29 [7]

Answer:

The 6th term of the sequence is 25

Step-by-step explanation:

first term = a = 5

common difference = d = 4

The nth term of a sequence is

T_n = a + (n - 1)d

Therefore, the 6th term of the sequence is

T_6 = a + (6 - 1)d

T_6 = a + 5d

T_6 = 5 + 5(4)

T_6 = 5 + 20

T_6 = 25

The average rate of change of credit card is $ 401.79 /year.

<h3>What is Average Rate?</h3>
  • A single rate that is a weighted average of the different rates that are applicable to property in various locations.
  • An average is a single number calculated as the average of a set of numbers, typically calculated as the sum of the numbers divided by the total number of numbers in the set (the arithmetic mean).

<u>Solution</u>

The difference of credit card debt between the year 2006 and 1992 = 8900 - 3275 = $5625

The difference of years between the year 2006 and 1992 = 2006 - 1992 = 14

average rate of change of credit card debt with respect to time = \frac{difference of credit card debt}{difference of years}

average rate = \frac{5625}{14} = $ 401.79 / year
