Answer:
14
Step-by-step explanation:
(5-x) +11 = 14
<span>A. periodic; about 6</span>
So an exponential equation is gonna be used for this problem. The formula for such is
![y=ab^x](https://tex.z-dn.net/?f=y%3Dab%5Ex)
, in which the a variable is the initial value and the b variable is the growth/decay rate.
For this situation, 1200 is gonna be your a variable since you've started out with it. And as for your b variable, its gonna be 107.3%, or 1.073, since it's increasing.
Your equation should look like this:
![y=1200(1.073)^x](https://tex.z-dn.net/?f=y%3D1200%281.073%29%5Ex)
and from here just plug in 10 into the x variable and solve.
Multiply (1.073)^10 (don't round answers until the end), and take that answer and multiply it with 1200, your answer should be $2427.61.
