Step-by-step explanation:

Effective rate: .058/2 = .029

This question is kind of ambigous and I'll make the assumption that there is no payment at time 0

\begin{gathered}175000=x\frac{(1+.029)^{2*18}-1}{.029}\\x=2821.511\end{gathered}

175000=x

.029

(1+.029)

2∗18

−1

x=2821.511

interested earned:

175000-2821.51*36= 73425.64

2.)

Same assumption as question 1 (there is no payment at time 0)

effective rate: .063/12= .00525

400(\frac{(1+.00525)^{60}-1}{.00525})=28124.24400(

Interest earned: 28124-400*60=4124.24

no he doesnt because "-16' is negatiive

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
