solve this inverse function, an environmental accident cause pollution to spill into a lake. The cost in millions of dollars, to remove x% of the pollution is given by the formula, c=f(x)=12.5x/100-x. calculate f^-1(50) and give a practical interpretation of the value.

9. An environmental accident cause pollution to spill into a lake. The cost, in millions of dollars, 12‘5”” . Calculate f&quot;(50) to remove x% of the pollution is given by the formula C = f(x) = 100- x and give a practical interpretation of the value. (A) f &quot; (50).: 80. At a cost of \$80 million, one can remove 50% of the pollution.(B) f 4 (50)- 80. At a cost of \$50 million, one can remove 80% of the pollution. (C) f ‘1 (50) – 12,5. At a cost of \$50 million, one can remove 12.5% of the pollution.(D) f‘1(50) = 12.5. At a cost of \$12.5 million. one can remove 50% of the pollution.
