Stereo price: $350
Discount: 20%
Sales tax: 6%
We first apply the discount to the initial price:
Discount = 20% of $350 = 20*350/100 = 70
The final price is:
Final_price = Initial_price - Discount
Final_price = 350 - 70
Final_price = $280
Now, we apply the sales tax to this price:
tax = 6% of $280 = 6*280/100 = $16.8
Now, the total price is:
Total_price = Final_price + tax
Total_price = 280 + 16.8
Total_price = $296.8
