The formula for exponential decay is

where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)

<span>y </span>≈ <span>13351.62</span>
The square root -38 is sqrt(38)i, or approximately 6.2i.
Also can I plz get brainiest?
Answer: -0.07142857142
I looked the question up on google ;)
100% - 60% = 40%
40% = 85
1% = 85 / 40
100% = 85/ 40 × 100
100% = $ 212.5.
