The percentage that the quantity demanded of starships will change is 4.62%.

Below is the equation for cross-price elasticity, and when we put in the XED of 0.66 and the percentage change in price of 0.07 we can solve for the change in quantity demanded of starships.

XED=%Change Quantity Demanded of starships/%Change in Price of spaceships

0.66=%Change Quantity Demanded of starships/.07

0.66*(.07)=%Change Quantity Demanded of starships

0.0462=%Change Quantity Demanded of starships
