Final answer:
The regular selling price of the television was $548.33
Step-by-step explanation:
To find the regular selling price of the color television, we can set up an equation using the information given. Let's say the regular selling price is P. According to the problem, the television is marked down by 40%, so the sale price is 60% of the regular price.
We can express this as an equation:
0.60P = $329.00
To find the value of P, we can divide both sides of the equation by 0.60:
P = $329.00 ÷ 0.60 = $548.33
Therefore, the regular selling price of the television was $548.33.
