Which error did Juanita make?

O She subtracted instead of added.

O She aligned the decimal points incorrectly.

O She did not regroup correctly when subtracting.

O She made a computational error when subtracting.

I’m pretty sure it’s D she made a computational error when subtracting.

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
