The value of a car is $21,500. it loses 12% of its value every year. show complete work. (a) write a function that represents the value y (in dollars) of the car after x years. (b) use the function to estimate the value of the car after 6 years. (round your answer to the nearest whole number)

The function is y=21500(1-0.12)ˣ, and the value after 6 years would be 9985.

The general form of the function is y=a×bˣ, where a is the initial value, b is the rate of increase (in this case, decrease) + 1, and x is the number of years.

Substituting 6 for x, we have:
y=21500(1-0.12)⁶=21500(0.88)⁶=9984.69≈9985.

Maybe the answer is 20mm. all i really did was just multiply, which is obvious.
