Sure! Let's solve for [tex]\( y \)[/tex] using the given equation step-by-step:
The equation provided is:
[tex]\[ 20,000 \times 0.01 \times y = 4,000 \][/tex]
First, let's simplify the left side of the equation. Multiply the car price ([tex]$20,000) by the commission rate (1%, which is 0.01 in decimal form):
\[ 20,000 \times 0.01 = 200 \]
So the equation now becomes:
\[ 200 \times y = 4,000 \]
Next, to solve for \( y \), divide both sides of the equation by 200:
\[ y = \frac{4,000}{200} \]
Divide the right-hand side:
\[ y = 20 \]
Therefore, \( y \) is 20, meaning Lee needs to sell 20 cars each month to earn $[/tex]4,000 per month.
So, the correct answer is:
(C) 20
