Answer:
The correct option is, Exponential Decay, $23,914.85.
Step-by-step explanation:
A farmer buys a tractor for $50,000.
It is provided that the the tractor depreciates 10% per year.
The exponential function for decay is:

Here,
a = initial value
r = decay rate
t = time
Compute the value of the tractor in 7 years as follows:


Thus, the correct option is, Exponential Decay, $23,914.85.
Increase.
1/4 can be translated to 25%
1/2 can be translated to 50%
25% to 50% is an increase.

a 3,5,5,11
b 3,3,37,3
- 2,269
d 113, as it is a prime factor
