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%)
