A small theater company sells tickets to a show.  They have a 400 seat theater and fill to 80% capacity.  Each ticket cost $30.  They repeated the same performance 2 other days.  How much did they make?
They sold 400*.8=<<400*.8=320>>320 tickets each day
So each day they made 320*30=$<<320*30=9600>>9600
They did 2+1=<<2+1=3>>3 days
So they made 9600*3=$<<9600*3=28800>>28,800
#### 28,800
