Calculate the effective rate of production for the following case of car imports. Suppose the unit value of a car is $100,000, unit cost of components is 70,000 . (1) When there is a 10 percent tariff on car imports and a 5 percent tariff on imports of components. What is the eiflective rate of protection? (2) When the tariff rate on the car imports and that on the components imports are both 5 percent, what is the effective rate of protection? (3) When the tariff rate on the car imports are 3 percent while that on the components imports is 5 percent, what is the effective rate of protection
