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
