<h3>How to analyze a differential equation</h3>
<em>Differential</em> equations are expressions that involve derivatives. In this question we must prove that a given expression is a solution of a <em>differential</em> equation, that is, substituting the variables and see if the equivalence is conserved. 
If we know that  and
 and  , then we conclude that:
, then we conclude that:

Answer:
30%
Step-by-step explanation:
7+14+9=30
10% of 30 is 3. 
3 goes into nine 3 times so you times 10% by 3 to get 30%.
