a $200 e - reader is sold in bulk to your store for $186. calculate the trade discount rate.\n?%
Answer
Explanation:
Step1: Calculate discount amount
The discount amount $d$ is the difference between the list - price $L$ and the net price $N$. Here, $L = 200$ and $N=186$. So, $d = L - N=200 - 186=14$.
Step2: Calculate discount rate
The discount rate $r$ is calculated by the formula $r=\frac{d}{L}\times100%$. Substitute $d = 14$ and $L = 200$ into the formula: $r=\frac{14}{200}\times100%$. First, $\frac{14}{200}=0.07$, then $0.07\times100% = 7%$.
Answer:
$7$
