Answer:
-80
Step-by-step explanation:
We have: -6 = + 4. In order to solve for x, we need to isolate it; in order to isolate x, we have to "undo" order of operations.
The regular order of operations is PEMDAS: parentheses, exponents, multiplication, division, addition, subtraction.
Here, since we're solving for x, we need to go backwards. So, first, subtract 4 from both sides:
-6 - 4 = + 4 - 4 ⇒ -10 =
Then, multiply by 8 on both sides:
-10 * 8 = * 8 ⇒ x = -80
Thus, x = -80.
Hope this helps!

So an exponential equation is gonna be used for this problem. The formula for such is 
, 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:
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.
