Answer 2

Answer-

14,202 newspapers will be sold in 2030.

Solution-

In 2015 the amount of newspaper sold was 25,000 and the number is expected to decline at a rate of 3.7% each year.

Taking,

x = number of years after 2015,

y = amount of newspaper sold.

A decay function of x and y can be obtained as follows,

$\Rightarrow y=25000(1-\frac{3.7}{100})^x =25000(96.3)^x$

Putting the value of x = 15 (as 2030-2015), we can get the value of y or the number of newspaper sold,

$\Rightarrow y=25000(96.3)^{15}=14201.503\approx 14,202$
