Final answer:
The student's question seems to misalign with the provided details, which relate to solving for equilibrium price and quantity using supply and demand equations, and applying the budget constraint equation. The original question about creating a matrix for baker income was not addressed due to lack of relevant information.
Step-by-step explanation:
It appears there might be some confusion with the question provided, as the information given mostly relates to supply and demand equations, not matrix multiplication or the calculation of income for bakers. To answer the question based on given information, we assume we need to solve for the market equilibrium where supply equals demand (Qs = Qd), and use a budget constraint equation.
To find the equilibrium price (P), we set the supply function Qs = 2 + 5P equal to the demand function Qd. Once we solve for the equilibrium price (P), we can determine the quantity supplied and demanded at that price by substituting back into either the Qs or Qd equations.
For the budget constraint, the income of an individual spending on two items is expressed as P1xQ1 + P2xQ2, where P1 and P2 are the prices of the items and Q1 and Q2 are the quantities purchased. This reflects the total expenditure on the items, which must not exceed the individual's budget.
