Gilberto owns a water pump. Because pumping large amounts of water is harder than pumping small amounts, the cost of producing a bottle of water rises as he pumps more.
Here is the cost he incurs to produce each bottle of water:
Cost of the first bottle $1
Cost of the second bottle $3
Cost of the third bottle $5
Cost of the fourth bottle $7
