Adaily newspaper has 10225 subscribers when it began publication. six years old later it has 8200 subscribers what is the average yearly rate of change in the number of subscribers for the six year period

The rate of change in number of subscriber for the six years is 3.62%

Step-by-step explanation:

Given as :

The initial subscriber of newspaper = p = 10225

The subscriber of newspaper after 6 years of publish = P = 8200

The time period = t = 6 years

Let The average yearly rate of change = r%

Now, According to question

The subscriber of newspaper after n years = initial subscriber ×

Or, P = p ×

Or, 8200 = 10225 ×

Or, =  

Or, 0.80195 =  

Taking power both side

So, =

Or, 0.9638 = 1 -

Or,   = 1 - 0.9638

Or,   = 0.0362

Or, r = 0.0362 × 100

i.e r = 3.62

So, The rate of change in subscriber = 3.62%

Hence, The rate of change in number of subscriber for the six years is 3.62% . Answer

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
