Answer:
<em>The amount to be paid is rupee 1872.72</em>
Step-by-step explanation:
<u>Compound Interest
</u>
It occurs when interest in the next period is earned on the principal sum plus previously accumulated interest.
The formula is:
![\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%3DP%5Cleft%281%2B%7B%5Cfrac%20%7Br%7D%7Bn%7D%7D%5Cright%29%5E%7Bnt%7D%7D)
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
The initial amount is P=1800 at r=8% = 0.08 during t=6 months (t=0.5 years) compounded quarterly. There are 4 quarters in a year, thus n=4.
Calculating A:
![\displaystyle A=1800\left(1+{\frac {0.08}{4}}\right)^{4*0.5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%3D1800%5Cleft%281%2B%7B%5Cfrac%20%7B0.08%7D%7B4%7D%7D%5Cright%29%5E%7B4%2A0.5%7D)
![\displaystyle A=1800(1.02)^{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%3D1800%281.02%29%5E%7B2%7D)
A = 1872.72
The amount to be paid is rupee 1872.72
Before we calculate we can use some common sence thinknig to narrow down the choices. We know that Robert is gonig DOWN the hill, so it doesnt make sence that he woudl have a positive rate of change (i.e. the number feet up the hill he is is decreasing, not increasing) So right away, A & B are clearly wrong.
If we look at the last two (C & D) we can see that if -460 were right after 10 minutes he would have walked down 4,600 feet. This is WAY more that the total height of the hill and so can't be correct.
So C must be correct.
We can check this with some simple math:
