You need to set up a system of equations. No one knows how many of each type of bill there is. Let t=twenties and f=fifties.
t+f=36
20t+50f=1170
-20(t+f=36)=-20t+-20f=-720
20t+50f=1170
30f=450 f=15
t+15=36
-15 -15
t=21
t+f=36
20t+50f=1170
-20(t+f=36)=-20t+-20f=-720
20t+50f=1170
30f=450 f=15
t+15=36
-15 -15
t=21
