Answer: Third Option
Step-by-step explanation:
We have the following exponential equation
We must solve the equation for the variable x
To clear the variable x apply the 
function on both sides of the equation
Simplifying we get the following:
To simplify the expression 
we apply the base change property
This means that:
Then:
<span>So we need to see how does the decimal point change it's place in the quotient when we divide any number by increasing powers of 10. Lets start with number 1. The decimal point is: 1.0 and when we divide by 10^1=10 we get 1/10=0.1. The decimal point has moved one place to the left. Now lets divide 1 by 10^2 and we get 1/100=0.01. Again, the decimal point has moved one more place to the left. Now: 1/10^3 = 1/1000 = 0.001. Next would be 0.0001, next one would be 0.00001 and so on. </span>
Answer:
This is a 25% decrease
Step-by-step explanation:
percent change = (old - new)/old * 100 %
The new price is 15
The old price is 20
Since the new price is less than the old price, it is a decrease
percent change = (20-15)/20 * 100 %
= 5/20 * 100%
=.25 * 100%
= 25%
This is a 25% decrease
