The function g(x) = 12,500(0.91)x represents the value of a piece of farm equipment after x years. Approximately when will its value be half its original value? A.
8.1 years

B.
7.3 years

C.
4.6 years

D.
3.9 years

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 :

Using logarithm properties :

⇒

⇒

≅

The correct option is B. 7.3 years

mean, 40.6

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!
