store mixes two kinds of toffee, A and B. Type A is priced at 1.65 yuan per serving of 100 grams; Type B is priced at 1.2 yuan per serving of 100 grams. It was originally planned to mix two parts of type A with one part of type B, but later changed the mixing method and mixed one part of type A into two parts of type B.
