Answer: $12
Step-by-step explanation:
The formula to calculate the compound interest , if the interest is compounded semi-annually :-
![A=P[(1+\dfrac{r}{2})^{2t}-1]](https://tex.z-dn.net/?f=A%3DP%5B%281%2B%5Cdfrac%7Br%7D%7B2%7D%29%5E%7B2t%7D-1%5D)
, where P = Principal amount
r = rate of interest ( in decimal)
t= Time ( in years)
Given : P= $1500
r= 1.6 % =0.016
t= 6 months = 
year [∵ 1 year = 12 months]
Then, the interest earned by Robert in 6 months will be :-
![A=1500[(1+\dfrac{0.016}{2})^{2\cdot\frac{1}{2}}-1]](https://tex.z-dn.net/?f=A%3D1500%5B%281%2B%5Cdfrac%7B0.016%7D%7B2%7D%29%5E%7B2%5Ccdot%5Cfrac%7B1%7D%7B2%7D%7D-1%5D)
![A=1500[(1+0.008)^{1}-1]](https://tex.z-dn.net/?f=A%3D1500%5B%281%2B0.008%29%5E%7B1%7D-1%5D)
![A=1500[1.008-1]](https://tex.z-dn.net/?f=A%3D1500%5B1.008-1%5D)
![A=1500[0.008]=12](https://tex.z-dn.net/?f=A%3D1500%5B0.008%5D%3D12)
Hence, Robert earned $12 as interest .

Answer:
F = 1.25
Step-by-step explanation:
All you would have to do is cross multiply, so our equations starts at 
. We would now multiply F by 8 and 2 by 5. We now have 8F = 10. We can now divide both sides of the equation by 8 to get F = 1.25.
