Sam is going on a 1,200 mile road trip with 2 friends, who he will pick up 100 miles after he begins and drop off when there are 100 miles remaining.
The car consumes 2 gallons of gas for every 50 miles, and gas costs $2.50
per gallon. Same will pay for all of the gas when he is alone in the car, but
he and his friends will split the cost evenly when they are together. How
much will Sam pay for gas? *

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
