Answer:
To find the discount, you need to first calculate the sale price of the karaoke machine by multiplying the regular price by the discount percentage and then subtracting that amount from the regular price.
The sale price of the karaoke machine is $156 x 35% = $<<15635.01=54.60>>54.60
So the discount is $156 - $54.60 = $<<156-54.6=101.40>>101.40.
Therefore, the correct answer is $101.40
