Answer:
The answer
Step-by-step explanation:
the width of a rectangular prism which has a height of 10 feet and a length of 14 feet should be 140 square feet
37=blue+red+green
37-red-blue=green
37-13=10=green
14=green
green:red=
14:10=
7:5
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 answer is between B and C but... I'm kinda leaning more towards B but, you choose which one you think is right.
Hope I helped you. :)
