Question 152240: The anual cost in dollars for removing p% of the toxic chemicals from a town's water supply is given by the formula
C(p) = (500,000)/100-p
use the formula to determine the cost for removing 99.5% of the toxic chemicals
I did C(99.5) = (500,000)/100-99.5
99.5 C = 500,000/.5
C = 1005.025
this just can't be right because It costs 50,000 at 90% and 100,000 at 95%
