a $100 smart home speaker is sold in bulk to your store for $92. calculate the trade discount rate. ?%
Answer
Explanation:
Step1: Calculate discount amount
The original price is $100 and the discounted - price is $92. The discount amount $d$ is the difference between the original price $P$ and the discounted price $S$. So, $d = P - S=100 - 92 = 8$.
Step2: Calculate discount rate
The discount rate $r$ is calculated by the formula $r=\frac{d}{P}\times100%$. Substitute $d = 8$ and $P = 100$ into the formula. Then $r=\frac{8}{100}\times100%=8%$.
Answer:
8%
