Solution :

Let the equation be written as,

 and    

Plot the equations (1) and (2),

The equation    plotted with blue line.

The   plotted with red line.

Refer the attached figure below.

The solution of equation is given by intersection point i.e. (0.4798,0.5903).

The solution is approximately x =0.5.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

the answer is 13 cm
