Suppose you start an ice cream business. you buy a freezer for $200. it costs you $0.45 to make each single-scoop ice cream cone. you sell each cone for $1.25. how many cones do you need to sell to break even?

Break-even is the point when in business there is no profit no loss situation.  
Given: - 
Cost of freezer = $200
 Cost to make one scoop ice-cream cone = $0.45
 Cost of selling each cone = $1.25 
 Solution: -
 To reach break-even one must earn at least $200 
 By above information we get profit on each cone = Cost of selling cone- Cost
of making each scoop
  =$1.25-$0.45
 =$0.80 = profit earned on each cone. 
 To earn $200 we must sell = $200/$0.80 = 250 cones.  250 cones are needed to sell to reach break-even.
