Answer: The probabilities of winning a contract are

Let the Probability of C winning the contract - P(C) be 'X'
Then,
Probability of B winning the contract - P(B) will be '7X' and
Probability of A winning the contract - P(A) will be 
Since the total of all the probabilities is 1,




So,

I used an excel spreadsheet since there is not enough room here.
Explanation:
The US started collecting federal income tax in 1913
Answer:
the price will grow to $ 507,571.77 If it continues with the same grow rate
Explanation:
first we solve for the rate:
2006 - 1895 = 111 years
![Nominal (1+r)^{n} = FV\\150 (1+r)^{111} = 70,000\\\\r = \sqrt[111]{70,000 / 150 } -1](https://tex.z-dn.net/?f=Nominal%20%281%2Br%29%5E%7Bn%7D%20%3D%20FV%5C%5C150%20%281%2Br%29%5E%7B111%7D%20%3D%2070%2C000%5C%5C%5C%5Cr%20%3D%20%5Csqrt%5B111%5D%7B70%2C000%20%2F%20150%20%7D%20-1)
r = 0.06
Now we apply this rate for the year 2040:
2040 - 2006 = 34 years
Principal 70,000.00
time 34.00
rate 0.06000
Amount 507,571.77
