Suppose that when income increases from $2900 to $3100 quantity demanded changes from 190 to 200.

Using the mid-point elasticity approach, calculate income elasticity.

Hint

Suppose that the income increases from $2600 to $3250. As a result, quantity demanded changes from 210 to 250.

Based on this information you can tell that this products is:

Hint

Suppose that the price of one product increases from $30 to $49. As a result, quantity demanded for another product changes from 200 to 210.

Based on this information, calculate cross-price elasticity:

Hint

Suppose that the price of one product increases from $28 to $38. As a result, quantity demanded for another product changes from 140 to 220.

Based on this information you can tell that these two products are:
