10x6=60 pounds
36x12=432 ounces which is 27 pounds
60+27=87
$22.50
20 pounds -12.00
50 pounds-.50
30 pounds since there is 17 pounds left -10

Determine the domain:<br><br><img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Cfrac%7Bln%28ln%28x%20%2B%201%29%29%7D%7Be%

The denominator cannot be zero, so

$e^x - 9 = 0 \implies e^x = 9 \implies x = \ln(9)$

is not in the domain of $f(x)$ .

$\ln(x)$ is defined only for $x>0$ , and we have

$\ln(x+1) > 0 \implies e^{\ln(x+1)} > e^0 \implies x+1 > 1 \implies x>0$

so there is no issue here.

By the same token, we need to have

$x+1 > 0 \implies x > -1$

Taking all the exclusions together, we find the domain of $f(x)$ is the set

$\left\{ x \in \Bbb R \mid x > 0 \text{ and } x \neq \ln(9)\right\}$

or equivalently, the interval $(0,\ln(9))\cup(\ln(9),\infty)$ .
