Final answer:
To calculate the cost of insurance for a new car, multiply the cost of the car by the insurance rate as a decimal. For a $20,000 car at a 23% rate, the first year insurance cost is $4,600.
Step-by-step explanation:
The cost of insurance for a new car that costs $20,000, which is 23% of the car's cost, can be calculated as follows:
- First, convert the percentage to a decimal by dividing by 100, resulting in 0.23.
- Multiply the car's cost by this decimal: $20,000 * 0.23 = $4,600.
Therefore, the cost of insurance for the first year is $4,600.
