The following graphs show his marginal utility curves for soda and coffee. At his current consumption level, Antonio's marginal utility from consuming the last can of soda he bought is MUS=12 utils per can, and his marginal utility from consuming the last cup of coffee he bought is MUC=12 utils per cup
