Final answer:
The documentary fee in Colorado is described with four different rates, but the correct rate must be confirmed with an official source as it can vary. Multiplying the selling price by the rate, if in decimal form, or calculating the percentage of the selling price will give the documentary fee.
Step-by-step explanation:
The question you're asking is related to the documentary fee that is charged in Colorado when a vehicle title is transferred. To find out which rate applies, we need to do a simple mathematical exercise. The options provided are rates in different formats: a decimal represented as a percentage, two are decimals, and one is a direct percentage.
For the rates given as decimals (0.0001, 0.01, and 0.001), you would multiply these by the selling price to get the fee. The 10% rate is already in percentage format, so you would just calculate 10% of the selling price. To select the current documentary fee rate in Colorado for a vehicle title transfer, you should verify this information from a reliable source specific to the state, as it can differ or change over time.
