Please help me solve out this question.

Suppose that we are considering the markets for both ) bears and ji rice Suppose that we observe that the price of rice rises from $2 per unit to $6 per unit. The price of beans remains at $4 per unit. Suppose that the quantity demanded of rice decreases from 28 units to 17 units Suppose also that the quantity demanded of beans also decreases from 30 units to 14 units. Calculate the cross-price elasticity of demand for this change for beans with respect to rice. Note: round your answers to two decimal places
