Sam has purchased a $30,000 car for his business. the car depreciates 30% every year. what is the explicit formula for this sequence? note: the car is 0 years old when purchased so the first year is the second entry in the sequence.

if your just figuring out how much the car depreciated just by driving off the lot new...1st year.

$30,000×.30=$9,000

$30,000- $9,000=$21,000.

just take the brand new value of the car multiplied by the .30% of the 1st depreciation...take that answer ($9,000) and subtract it from your original value of $31,000.

which gives you $21,000
