Answer:
B. 7.3 years
Step-by-step explanation:
The question is wrong. The correct function is :
We have the function 
that represents the value of a piece of farm equipment after 
years.
This means that when 
its original value is :
Now we want to calculate approximately when will its value be half its original value. Then, we write :
is half of its original value. We need to find that satisfies the following equation :
Solving for :
⇒
Now we apply natural logarithm to each side of the equation :
![ln(0.5)=ln[(0.91)^{x}]](https://tex.z-dn.net/?f=ln%280.5%29%3Dln%5B%280.91%29%5E%7Bx%7D%5D)
Using logarithm properties :
⇒
![ln(0.5)=x[ln(0.91)]](https://tex.z-dn.net/?f=ln%280.5%29%3Dx%5Bln%280.91%29%5D)
⇒
≅ 
The correct option is B. 7.3 years
This is the concept of exponential functions; The statements that are correct about the exponential decay functions are:
1. The domain is all real number
4. The base must be less than 1 and greater than 0
5. The function has a constant multiplicative rate of change

Answer: 164.4 or 165
Step-by-step explanation: So, you do 226 x 3 and you get $678. So now that you know that you have $678 worth of student tickets, you want to find how much more you need for the adult tickets, so you do $1500-$678, and you get $822. Divide it by 5 and you get 164.4, so you wanna sell about 165 tickets. Check your work by multiplying 5 by 165 and you get $825, which meets your $1500 minimum
