Antonio owns a water pump. Because pumping large amounts of water is harder than pumping small amounts, the cost if producing a bottle of water rises as he pumps more. Here is a cost he incurs to produce each bottle of water: Cost of first bottle: $2
Cost of second bottle: $4
Cost of third bottle: $6
Cost of fourth bottle: $8
