Answer:
The demand for good A will be elastic. Demand for good B will also be elastic.
Explanation:
A firm produces and sells two goods, A and B.
Good A is known to have many close substitutes; good B makes up a significant portion of most families' budgets.
Since good A has a lot of substitutes an increase in its price will lead to a reduction in its quantity demanded as people will prefer a cheaper substitute. This will make its demand elastic.
Good B makes a significant portion of the families' budgets. So a change in its price will significantly affect the budget of the families. This will make its demand relatively elastic.
