我直接微分可以算出正確答案b，但如果把等號左右一起除x後再微分就算不出來了🥲。 是不能這樣除嗎…（我覺得是可以的吧）還是我哪裡算錯了… btw第一張照片是題目跟解答 第二張是我用同除x的算法！

2024 個體經濟學 0911 作業 請於 0918 上午8點前,在iLearning 上傳你的答案。 Each month a person consumes cosmetics (x1) and food (x2). The prices are p₁ = 100 and P21. Her monthly income is w = 8000. A department store is having a promotion this month. For every $2000 cash payment on cosmetics, the person can get a coupon of $200. So, if a person pays $4000 cash to buy cosmetics, she can get two $200 coupons. But if she pays $3999 cash to buy cosmetics, she gets only one $200 coupon. If she uses $3800 cash and one $200 coupon to buy cosmetics, she can get x₁ = 40 and one $200 coupon. The coupons expires at the end of this month and cannot be sold to others. x₁ and x2 can be any positive real number or 0. 1. Suppose that the coupon can be used on cosmetics only. Draw the person's budget con- straint. 2. Suppose that the coupon can be used on cosmetics or food. Draw the person's budget constraint. 3. Are both budget sets convex?
