Explanation:

The technique I use in solving these problem is working backwards. I'm given the total amount to I set the rest of the equation to said amount. Another piece that we are given is the wage. This number is independent from any other number, therefore we can leave it by itself on the other side of the equation.

$3000=$400x

We are given a commission amount, this number is dependent on another number, and that's the number we're looking for.

$3000=$400 (1//6x)

Now that our equation is set, we can begin solving by isolating our variable.

$3000-$400=(1/6x)

=$2600=(1/6x) =($2600)/(1/6)=$x$

x=\$15600
