Actually none of the answers is correct - it's neither 30,900 nor 40,000.
30,944 rounded to the nearest ten thousand will give us 30,000. It's because 30,944 is closer to 30,000 than to 40,000.
Dan pays $5 more than Barney because his membership fee is $35, while Barney's is only $30.
The answer is $5.
Given:
Amount borrowed (P)= $25000
Rate of interest (r)= 6%
Time (t)= 4 years.
To find:
The total interest the company pay in all.
Solution:
We know that,
![A=P(1+r)^t](https://tex.z-dn.net/?f=A%3DP%281%2Br%29%5Et)
where, A is amount, P is principal, r is rate of interest and t is time period.
![A=25000(1+\dfrac{6}{100})^4](https://tex.z-dn.net/?f=A%3D25000%281%2B%5Cdfrac%7B6%7D%7B100%7D%29%5E4)
![A=25000(1.06)^4](https://tex.z-dn.net/?f=A%3D25000%281.06%29%5E4)
![A=25000(1.26247696)](https://tex.z-dn.net/?f=A%3D25000%281.26247696%29)
![A=31561.924 ](https://tex.z-dn.net/?f=A%3D31561.924%0A)
Now,
![I=A-P](https://tex.z-dn.net/?f=I%3DA-P)
![I=31561.924-25000](https://tex.z-dn.net/?f=I%3D31561.924-25000)
![I=6561.924](https://tex.z-dn.net/?f=I%3D6561.924)
Therefore, the total interest is $6561.924.
