20 = n/4. Solve for n using reverse operations. Show all work. Your answer

n=80

Step-by-step explanation:

n/4=20

(n/4=20)4 .    to get rid of the denominator u multiply by 4 on both sides

n=80

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
