, what value of x would make the equation undefined?
Hint: Think about what makes an equation undefined. Then calculate what value would make this equation undefined.
Any ideas????? help
The cost, in millions, to remove x% of pollution in a pond is modeled by the equation: C=6350/(425-3x)
What is the cost to remove 75% of the pollution? Plug in and calculate, do not convert to a decimal.

obviously the denominator cannot be zero.
That would happen when 425 - 3x= 0 or when x = .75
cost = 6350/(425 - 3(.25)) = 14.967
it would cost about 15 million
