The marl-tat for USB ash driyes in Country C is perfectly competitive and is in equilibrium. Domestic demand is given by Car = sec 4F and domestic supply is giyen by 03 = 2F! The 1world price for ash driyes is $20. Country C wishes to 'protect' its domestic esh memory industry. Cine policy option is to impose a tariff on all USE esh driyes imported into country C from country A {the only other country that produces esh driyes]. The neydy-elected goyernment of country C wishes to avoid tariffs, as it was elected partially on a 'free-trade' {no tariff} platform. Country C agrees to forego any tariff on ash drives if country A sellers 'yoluntarily' restrict sales of ash driyes into country C. Country A agrees to sell no more than 120 ash drives to country C buyers.
