Trey is a car salesman who earned a base pay of $47,300 and was paid
commission of 15% for each car he sold. if x represents total sales in dollars,
then which of the following equations best represents trey's total pay in
dollars?

Trey earns a base pay of $47,300 plus 15% for each car sold.

The equation that represets Trey's total pay in dollars is:

y = $47,300 + 0.15x

Where $47,300 represents the base pay, and 0.15x represents the money he earn for the total cars sold.

Step-by-step explanation:

Let x represent total sales in dollars.

We have been given that Trey earns base pay of $47,300 and was paid  commission of 15% for each car he sold.

Since Trey is paid 15% for each car he sold and total sales were x dollars, this means his commission would be 15% of x that is .

The total salary of Trey would be base salary plus commission:

Therefore, the equation represents Trey's total pay in dollars.

Jason can substitute into the equation to check his answer. The left side of the equation must be equal to the right side of the equation.

Step-by-step explanation:

The equation must be solved by calculating the value of  x:

Add like terms:

Divide both sides by -12:

Now he can substitute into the equation and simplify to check his answer.

If his answer is right, the left side of the equation will be equal to the right side of the equation.

Then:

 is a solution of the equation.
