Answer:
We can not solve for a unique cost for each soldier.
Step-by-step explanation:
Let x be the daily cost for legionaries and y be the daily cost for archers.
Upon using our given information we will get a system of linear equations as:


Now we will solve for x from our 2nd equation,

Now we will substitute this value in our 1st equation.

We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.
The formula is
A=p (1+r)^t
A future value 572.6
P present value 560
T time 6/12 =1/2=0.5
R interest rate?
We need to solve for r
R=(A/p)^(1/t)-1
R=(572.6÷560)^(1÷0.5)−1
R=0.0455×100
R=4.55%
