Afish tank holds 95 gallons of water but is losing 4 gallons per day. a second fish tank contains 40 gallons but has 5 gallons added per day. after how many days will the first fish tank have less water than the second.

the answe i =−n+5

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
