Answer:
Discount Rate=17%
Step-by-step explanation:
We know the price and discount of the car. The formula for calculating the discount when rate is given is:
[tex]Discount=Listed\ price*discount\ rate[/tex]
We know two quantities out of three, so putting in the known values:
[tex]3000=18000*rate\\rate=\frac{3000}{18000}\\Rate=16.67%[/tex]
The rate rounded off to nearest percent will give us:
17 percent.
So the discount rate is 17% ..
