Casey and david both ride all-terrain vehicles on trails every weekend for fun. each month, casey rides for a total of 2x hours at an average
speed of x miles per hour. david rides 4 more hours a month than casey, but at an average speed that is 3 miles per hour less than casey's
average speed. write the standard form of the function which describes the total distance, in miles, that david rides each month.

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
