Of the 100 soccer balls that Nova went to inflate, 40 percent had holes in them and could not inflate, while 20% of the remaining balls were overinflated and exploded. How many balls were inflated successfully and could be used?

How many balls had holes in them? ** If 40% of the balls had holes in them and could not inflate, their number was 40/100*100= <<40/100*100=40>>40
How many balls were left? ** The remaining balls that Nova could inflate were 100-40 = <<100-40=60>>60
How many balls were overinflated? ** While inflating, 20% of the good soccer balls were overinflated and exploded up, a total of 20/100*60 = <<20/100*60=12>>12
How many balls were inflated successfully? ** The number of soccer balls that inflated successfully and could be used is 60-12 = <<60-12=48>>48
