Note:

In first query you have to sell two hamburgers and three chicken burgers. Your income is $$$2 \cdot 5 + 3 \cdot 10 = 40$$$.

In second query you have to ell one hamburgers and two chicken burgers. Your income is $$$1 \cdot 10 + 2 \cdot 12 = 34$$$.

In third query you can not create any type of burgers because because you have only one bun. So your income is zero.
