Answer
Explanation:
Step1: Calculate discount amount
The discount rate is 20% or 0.2 in decimal form. The original price of the stereo is $320. The discount amount $d$ is calculated by multiplying the original price $p$ by the discount rate $r$. So $d = p\times r=320\times0.2 = 64$.
Step2: Calculate final price
The final price $f$ of the stereo is the original price $p$ minus the discount amount $d$. So $f=p - d=320-64 = 256$.
Answer:
$256$
