A contractor bought 7.6 ft to the second power of sheet metal. he has used 3.7ft to the scound power so far and has $117 worth of sheet metal remaining. The equation 7.6x - 3.7x =117 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?

step-by-step explanation:

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
