Jessica is organizing a guided tour of the rain forest. The average profit per person that the touring company makes is given by
Allushta [10]

As a practical equation, this one doesn't make much sense -- why would the profit per person have a term proportional to the number of people?  Let's just go with it.

18x + \dfrac{35}{x}

= \dfrac{18x^2}{x} + \dfrac{35}{x}

= \dfrac{18x^2 + 35}{x}

That's the answer to the first part.

35/x represents a portion of the profit that's 35/x per person, or a constant $35 per tour.

If 800g of a radioactive substance are present initially and 8 years later only 450g remain, how much of the substance will be p
artcher [175]

A=Pe^(rt)

P = 800g

t = 8 years

A = 450g

r = This is what we will try and find to start with

450=800e^(r*8)

After running the math through a calculator, we end with r = -0.07192

Now we just re-input this information into our equation: A=800e^(-0.07192*16)

A=800e^(1.15072)

Now we will re-write the equation using the negative exponent rule:

A = 800 1/e^1.15072

Combine right side:

A = 800/e^1.15072

Then do the math:

A = 253.12709836......

That will give us A = 253 (rounded to the whole number)

I hope this helps! :)
