The cost of cleaning up pollution in a stream is given by

anastassius [24]

Answer:

p must be less than 100

Step-by-step explanation:

Let

c ----> the cost in dollars to clean the stream

p ----> percent of the stream

we have

$c=\frac{370,000}{100-p}$

Remember that the cost cannot be a negative number

and

the denominator cannot be a zero

$100-p > 0$

Solve for p

Multiply by -1

$-100+p < 0$

Adds 100 both sides

$p < 100$

therefore

p must be less than 100
