Answer
Answer:
D. $20,000
Explanation:
Step1: Calculate commission on first $5000
$5000\times0.05 = 250$
Step2: Find commission on amount over $5000
$1375 - 250=1125$
Step3: Calculate amount of sales over $5000
Let $x$ be the amount of sales over $5000$. Then $0.075x = 1125$, so $x=\frac{1125}{0.075}=15000$
Step4: Calculate total sales
$5000 + 15000=20000$
