Answer:
a.) $630, $14700, $25200, $56700, $119700, $308700, $623700
b) It is impossible
c) find attached
Step-by-step explanation:
A formula that relates the percentage of pollutants removed to the cost of removing them
y=6.3x/(100-x)
Where y is the cost of removing the pollutants (in thousand dollars) and x is the pollutant percentage to be removed.
Putting 50% pollutant into the equation
y=6.3×50/(100-50)
y=$6.3 thousand or $6300
Putting 70% as x
y=6.3×70/(100-70)
y=$14700
Putting 80% as x
y=6.3×80/(100-80)
y=$25200
Putting 90% as x
y=6.3×90/(100-90)
y=$56700
Putting 95% as x
y=6.3×95/(100-95)
y= $119700
Putting 98% as x
y= 6.3×98/(100-98)
y=$308700
Putting 99% as x
y=6.3×99/(100-99)
y=$623700
b) Removing all the pollutants means removing 100% pollutants
Putting 100% as pollutant into the function, makes it undefined. Therefore 100%pollutant cannot be removed
y=6.3×100/(100-100)
y=630/0 (any fraction divided by zero os undefined)
