# Explanation:
## Step1: Convert percentage to decimal
The sales - tax rate is 8%, convert it to decimal form. $8\%=\frac{8}{100}=0.08$.
## Step2: Calculate the sales tax
Multiply the price of the MP3 player by the sales - tax rate. The price of the MP3 player is $150$, so the sales tax is $150\times0.08 = 12$.
