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

Remember that the cost cannot be a negative number
and
the denominator cannot be a zero
so

Solve for p
Multiply by -1

Adds 100 both sides

therefore
p must be less than 100
The perimeter of a triangle is:
P = a + b + c
We are given that:
b = a + 3
c = 2 a – 3
Therefore:
68 = a + a + 3 + 2 a – 3
68 = 4 a
a = 17
and,
b = a + 3 = 20
<span>c = 2a – 3 = 31</span>
