a new car that sells for \$18,000 depreciates 25% each year. write a function that models the value of the car. find the value of the car after 4 years

Let  the variable of time is  t and the prix is x so

f(t) = x - x * 0.25*t  so we have   x = 18 000\$

so f(t) = 18 000 - 18 000 * 0.25 * t = 18 000 - 4 500 * t

so the function is  f( t )= 18 000 - 4 500 * t

we have a car depreciates 25% each year so  18 000 * 0.25 =  4 500

so the prix of the car reduce with average of 4 500\$ each year so

after 4 years the value of the car is 18 000 - 4 500 * 4 = 0 \$
