[作業] 效用極大化的問題
An ice-cream lover has a total of $10 to spend one evening.
The price of ice-cream is $p per pint.
The person's preferences for buying q pints of ice-cream and then having
$(10-pq)to spend on other items,are represented by the utility function
U(q)=(q^1/2)+2*(10-pq)^1/2
求效用極大化的q
求效用極大化不是需要預算限制式 可是這題預算限制要怎麼看
只知道pq和10而以啊
需要自己假設一個P嗎??
