Explanation:
Part A
131.5 or $131,500 is the starting value of the plane X before it started to depreciate.
Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)
b (m) = 177,233 (0.024)^m
$177,233 is the starting value of plane Y.
The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.
Part C
b (t) = 177,233 (0.024 x 12)^t
b (t) = 177,233 (0.288)^t
I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.
That's it! I hope I'm right because this took a lot of thinking lol
