Answer:
10 + m  ≥ 30
You must spend AT MOST $20 or more
Step-by-step explanation:
Basically you have already spent 10 dollars and you have to pay MORE than or equal to 30. You cannot pay less than because you want the free songs. So the sign has to be  ≥ or the inequality will not be true. 
10 + m  ≥ 30
10 - 10 + m  ≥ 30 - 10     ( subtract 10 from each side to isolate m)
m  ≥ 20     ( we are left with this )
The answer is :
m  ≥ 20 
You must spend at most 20 dollars more to get the 3 free cd's. Your welcome :D
