$10-3x=2x-8x+20\\\\10-3x=-6x+20\ \ \ \ |subtract\ 10\ from\ both\ sides\\\\-3x=-6x+10\ \ \ \ |add\ 6x\ to\ both\ sides\\\\3x=10\ \ \ \ \ |divide\ both\ sides\ by\ 3\\\\x=\frac{10}{3}\\\\\boxed{x=3\frac{1}{3}}$

Answer:

Inequality: 0.08x + 2300 ≥ 2800

Liz needs to sell products of $6250 at least.

Step-by-step explanation:

Given that:

Per month salary of Liz = $2300

Commission = 8% = $\frac{8}{100}}$ = 0.08

Amount Liz wants to earn = $2800

Let,

x be the amount of sales.

0.08x + 2300 ≥ 2800

0.08x ≥ 2800 - 2300

0.08x ≥ 500

Dividing both sides by 0.08

$\frac{0.08x}{0.08}\geq \frac{500}{0.08}\\x\geq 6250$

Hence,

Liz needs to sell products of $6250 at least.

Anyone good at composite functions??

$\bf \begin{cases} ~\hfill f(x) = &-3x+4\\ ~\hfill g(x) = &x^2\\ (g \circ f)(0)=&g(~~f(0)~~) \end{cases} \\\\[-0.35em] ~\dotfill\\\\ f(0) = -3(0)+4\implies \boxed{f(0) = 4} \\\\\\ g(~~f(0)~~)\implies g\left( \boxed{4} \right) = (4)^2\implies \stackrel{(g \circ f)(0)}{g(4)} = 16$
