Areal estate broker’s base salary is $18,000. she earns a 4% commission on total sales. how much must she sell to earn $55,000 total? show your work and explain your reasoning in the space provided below.

$925,000

Step-by-step explanation:

Let "t" represent "total sales."

We are asking how much this person must bring in thru sales to end up with $55,000 in earnings.

A suitable equation would be:

$18,000 + 0.04t = $55,000.

Let's isolate t.  Start by subtracting $18,000 from both sides, obtaining:

0.04t = $37,000

Dividing both sides by 0.04 results in t = $925,000.

Her sales must be $925,000 for her income (including earnings) to be $55,000.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
