A

B. 413.52

Step-by-step explanation:

the net profit (ignore all other stuff): 106×6

the fee used for buying: 106×2

the advertising price: 10.48

 106×6-106×2-10.48

=636-212-10.48

=424-10.48

=413.52

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
