the cost of admission to funland park was $70 for a group of 2 adults and 5 children. the admission was $84 for another group of 4 adults and 3 children. write a system of equations that can be used to determine, a, the number of adults and c, the number of children.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

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
