The stereo system costs $256.
Step-by-step explanation:
Given:
Cost of the stereo system = $320.
The discount Zenaida received = 20%.
To Find:
Cost of the stereo system after the discount=?
Solution:
Step1: Finding the discount amount:
Discount percentage =20
Discount amount = original cost × discount percent
Substituting the values,
[tex]\text { Discount amount }=320 \times 20 \%[/tex]
[tex]\text { Discount amount }=320 \times \frac{20}{100}[/tex]
[tex]\text { Discount amount }=320 \times \frac{1}{5}[/tex]
[tex]\text { Discount amount }=320 \times 0.2[/tex]
[tex]\text { Discount amount }=64[/tex]
Step 2: Removing the discounted amount from the original price
Final cost of the stereo system =original cost of the stereo system –discount amount
Substituting the values we get,
Final cost=320-64
Final cost=256
Result:
Thus the cost of the stereo system after discount is $256
