We can only simplify this equation, since you haven't defined x.......

$15x - 0.3 + 100 \implies 15x + (100-0.3) \implies \boxed{15x + 99.7}$

Note that Density = $\frac{\text{population}}{\text{area}}$

As stated in the question, there are 15 lizards, and the area of the circle that surrounds the boulder is simply $14^2\times\pi$or $196\pi$Thus the answer is $\frac{15}{196\pi} \approx \frac{1}{41.0293333}$

$\frac{1}{4}$

_{IK so we need help} 

/bump i need help

Note that $x^{-y} \implies \frac{1}{x^y}$
