Final answer:
The registration fee for a used car with a sale price of $5,500 at a rate of 0.5% is $27.50. This is calculated by multiplying the sale price by 0.005.
Step-by-step explanation:
The registration fee for purchasing a used car is calculated as a percentage of the sale price. In this case, the fee is 0.5% of the sale price, which is $5,500. To find the fee, you multiply the sale price by the percentage:
Registration Fee = Sale Price × Registration Fee Percentage
Registration Fee = $5,500 × 0.005 (since 0.5% is the same as 0.005 in decimal form)
Registration Fee = $27.50
Therefore, the registration fee that needs to be paid for this used car is $27.50.
