Final answer:
The car's value after 5 years, considering a 30% annual depreciation rate with a common ratio of 0.70, will be approximately $5,042.10.
Step-by-step explanation:
The value of a car that depreciates by 30% per year can be calculated using the formula for geometric sequences, since depreciation in this case is a common ratio problem. In this scenario, the common ratio is 0.70 because each year the car retains 70% of its value from the previous year (100% - 30% depreciation = 70%). After 5 years, the car's value will be:
Value after 5 years = $30,000 × (0.70)^5
Now we calculate the value after 5 years step by step:
1. Calculate the common ratio to the power of the number of periods (years): (0.70)^5
2. Multiply the original value by the result from step 1.
Let's perform the calculations:
(0.70)^5 = 0.16807
Value after 5 years = $30,000 × 0.16807 = $5,042.10
So, after the fifth year, the car will approximately be worth $5,042.10.
