请问完全替代品的比例是看两个产品价格，还是看他如何消费，题例写着喝一个可乐或者吃两个披萨，但是价钱是披萨3元，可乐1元，无差别曲线应该怎么画？第二问是说Sook-Hee consumed too much Cola and Pizza. Now whenever Sook-Hee drinks Cola or eats Pizza she gets violently ill. The degree in which Sook-Hee isnegatively affected by two bags of Pizza is equal to the impact of a bottle of Cola. how does this change the picture you drew above?这种情况又应该怎么画？
