10. the value of a car, in dollars, x years after its purchase is represented by the function f(x) = 8000(0.55) x . what is the average decrease in value per year between years 1 and 2? (round to the nearest whole number)

Based on what i know about mean, this doesn't add up.

On average, how many more hits will he get when he bats 100 times at home during the day as opposed to 100 times away at night?
