The Russian air force is being called on this year to intercept storms advancing on Moscow and to seed them with dry ice and silver iodine particles. The idea is to make the snow drop on villages in the countryside instead of piling up in Moscow. The cost of this initiative will be 220 million rubles, and the savings in snow removal will be in the neighborhood of 350 million rubles. The exchange rate is 30 rubles per dollar. Comment on the hidden costs and benefits of such a plan from the viewpoint of the villagers in terms of dollars. The environmental impact on the villagers is unknown, but their spring and summer crop yields could be affected by more than normal snow melt. In case the total hidden cost is equal to or higher than $(answer) nothing million, the plan is no longer cost-effective when this additional externality is considered. (Round to two decimal places.)
