Problema Solution
the cost in millions of dollars, to remove x % of pollution in a lake modeled by C=6000/200-2x
1. what is the cost to remove 75 percent of the pollutant
2. what is the cost to remove 90 percent of the pollutant
3. what is the cost to remove 99 percent of the pollutant
For what value is this equation defined?
Answer provided by our tutors
C=6000/(200-2X) I'LL ASSUME THIS IS THE EQUATION.
C=6000/(200-2*75)
C=6000/(200-150)
C=6000/50
C=120 COST TO REMOVE 75%.
C=6000/(200-2*90)
C=6000/(200-180)
C=6000/20
C=300 COST TO REMOVE 90%.
C=6000/(200-2*99)
C=6000/(200-198)
C=6000/2
C=3000 COST TO REMOVE 99%.
THE EQUATION IS UNDEFINED WHEN YOU USE 100%.
C=6000/(200-200)
C=6000/0 C BECOMES UNDEFINED WHEN YOU IVIDE BY 0.
