Answer:
x = 417.6
Step-by-step explanation:
0.5*x = 287 -78.2
0.5*x =208.8
x=208.8/0.5 = 417.6
The salary in 2012 was $65,000.
If the inflation rate is 4%, the salary should increase at least 4% per year to keep up with inflation.
Then, we can calculate the salary adjusted by inflation in 2021 as:
![S_{2021}=S_{2012}\cdot(1+i)^{2021-2012}=S_{2012}\cdot(1+i)^9](https://tex.z-dn.net/?f=S_%7B2021%7D%3DS_%7B2012%7D%5Ccdot%281%2Bi%29%5E%7B2021-2012%7D%3DS_%7B2012%7D%5Ccdot%281%2Bi%29%5E9)
Replacing with the data, we get:
![\begin{gathered} S_{2021}=S_{2012}\cdot(1+i)^9 \\ S_{2021}=65000\cdot(1+0.04)^9 \\ S_{2021}=65000\cdot1.04^9 \\ S_{2021}\approx65000\cdot1.4233118 \\ S_{2021}\approx92515.27 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20S_%7B2021%7D%3DS_%7B2012%7D%5Ccdot%281%2Bi%29%5E9%20%5C%5C%20S_%7B2021%7D%3D65000%5Ccdot%281%2B0.04%29%5E9%20%5C%5C%20S_%7B2021%7D%3D65000%5Ccdot1.04%5E9%20%5C%5C%20S_%7B2021%7D%5Capprox65000%5Ccdot1.4233118%20%5C%5C%20S_%7B2021%7D%5Capprox92515.27%20%5Cend%7Bgathered%7D)
Answer: the adjusted salary to keep up with inflation should be $92,515.27 in 2021.
