Alyssa enjoys consuming both soda and coffee. Each can of soda costs PS=$1 , and each cup of coffee costs PC=$2 . Suppose that Alyssa buys 30 cans of soda and 20 cups of coffee per week. The following graphs show her marginal utility curves for soda and coffee. At her current consumption level, Alyssa's marginal utility from consuming the last can of soda she bought is MUS=12 utils per can, and her marginal utility from consuming the last cup of coffee she bought is MUC=12 utils per cup
