Company KW is being sold, and Companies x, y, and z are considering forming a merger to purchase it. The price of Company KW is 60% more than Company x has in assets, and this same price is also 100% more than Company y has in assets. Company x has an outstanding debt that's equivalent to 20% of its assets, while Company y owns stocks worth 30% of its assets. Additionally, Company z has assets worth 50% of Company y's assets, and has a 10% annual growth rate. Assuming one year has passed since the acquisition, if these three companies were to merge and combine their assets (including outstanding debts, stock values, and the growth rate of Company z), the price of Company KW would be approximately what percent of these combined assets?
