Jeff buys a car for $28,000. the vehicle depreciates by 16% each year. Which of the following is the common ratio of the sequence representing the car's value every year?

Find the value of the car in the next year

value next year = (100% - 16%) * 28,000

value next year = 84% * 28,000

value next year = 84/100 * 28,000

value next year = 23,520

The value of the car in the next year is $23,520

Find the ratio

ratio = value of next year/value of recent year

ratio = 23,520 / 28,000

ratio = 0.84

The ratio is 0.84, it's the same with the percentage of value in the next year (84%)
