I took the test

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,

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

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
