Well you have to find out how many cd is 40% and 30% 
30% = 30x.3=9
40% = 30x.4=16
now add 16 and 9
16+9=25 now subtract 25 from 30 and see that you have 5 cd of a different type of music to find that as a % divide 5 by 35 to get .14 I rounded it to the nearest hundreth now move the decimal over 2 spots to get 14%

 Answer:

Step-by-step explanation:
Given:  .
.
we need to find the correct form for  if the equation is solve using undetermined coefficients.
 if the equation is solve using undetermined coefficients.
A first order differential equation  is said to be homogeneous if
 is said to be homogeneous if  for all t.
 for all t.
Consider homogeneous equation 
Let  be the solution .
 be the solution .
We get 
Since  ,
