Betty picked 16 strawberries. Matthew picked 20 more strawberries than Betty and twice as many as Natalie. They used their strawberries to make jam. One jar of jam used 7 strawberries and they sold each jar at $4. How much money were they able to make from the strawberries they picked?
Matthew picked 16 + 20 = <<16+20=36>>36 strawberries.
Natalie picked 36/2 = <<36/2=18>>18 strawberries.
All together, they have 16 + 36 + 18 = <<16+36+18=70>>70 strawberries.
They can make 70/7 = <<70/7=10>>10 jars of strawberries.
They earn 10 x $4 = $<<10*4=40>>40 from the strawberries they picked.
