The value of a boat, in dollars, x years after its purchase is represented by the function.

f (x) = 10,000 (0.73) x

What is the average decrease in value per year between years 1 and 2?

Enter your answer in the box. Round to the nearest whole number.

The average decrease in value can be solve by first solving the value at year 1 and year 2

and i think the equation is f (x) = 10,000 (0.73) ^x

at x = 1

f (x) = 10,000 (0.73) ^x

f (1) = 10,000 (0.73) ^ (1)

f (1) = 7300

at x = 2

f (x) = 10,000 (0.73) ^x

f (2) = 10,000 (0.73) ^ (2)

f (2) = 5329

so the average decrease = (7300 - 5329) = $ 1971 per year
