Two-variable equations as models
example: miranda has 55 feet of fencing. she wants to use all the fencing to
create a rectangular garden. the equation 21 + 2w = 55, where t is the length of
the garden and w is the width, models the scenario. this equation can be used to
find one dimension of the garden if the other dimension is known.
think about constraints:
each side must be
than 0.
each side must be
then 27.5.
each side must be greater than a
inches.

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
