Answer:
c
Step-by-step explanation:
2a + 2s = 32, 6a + 7s = 106
Solve for a in the first equation.
2a = 32 - 2s
a = 16 - s
Substitute a into the second equation.
6(16 - s) + 7s = 106
96 - 6s + 7s = 106
96 + s = 106
s = 10
Substitute s into the first equation.
2a + 2(10) = 32
2a + 20 = 32
2a = 12
a = 6
a = 6, s = 10
Answer:
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
Step-by-step explanation:
The value needed to equal the value of 1 currency unit in 1917, in x years after 1990, is given by:
![V(x) = 0.4925x + 13.7485](https://tex.z-dn.net/?f=V%28x%29%20%3D%200.4925x%20%2B%2013.7485)
a) Use this function to predict the amount it will take in 2011 and in 2019 to equal the value of 1 currency unit in 1917
2011 is 2011 - 1990 = 21 years after 1990, so we have to find V(21).
![V(21) = 0.4925*21 + 13.7485 = 24.091](https://tex.z-dn.net/?f=V%2821%29%20%3D%200.4925%2A21%20%2B%2013.7485%20%3D%2024.091)
The amount it took in 2011 to equal the value of 1 currency unit in 1917 was of 24.091 currency units.
2019 - 1990 = 29, so we also to find V(29).
![V(29) = 0.4925*29 + 13.7485 = 28.031](https://tex.z-dn.net/?f=V%2829%29%20%3D%200.4925%2A29%20%2B%2013.7485%20%3D%2028.031)
The amount it took in 2019 to equal the value of 1 currency unit in 1917 was of 28.031 currency units.
