Answers

4x + 10= 2x - 6
Subtract 2x on both sides

4x - 2x + 10 = 2x - 2x - 6

4x - 2x + 10 = -6

2x + 10 = -6

chair he sells. The equation above gives Caden's annual salary. S. in dollars, after selling c dental

chairs. Based on the equation above, what is Caden's base salary?

Answers

Answer: $40,000

Step-by-step explanation:

Given : Caden started a new job selling dental chairs. He earns a base salary plus a commission for every chair he sells.

The equation gives Caden's annual salary. S. in dollars, after selling c dental chairs. : S = 40,000 + 500c

To find the base salary , we substitute c= 0  [i.e. if do not sell any chair.] in the above equation.

S = 40,000 + 500(0)

S = 40,000 + 0

S = 40,000

⇒ Caden's base salary= $40,000
