Sigrur plans to spend the evening watching the latest series of her favorite shows. She is on her way to the shop and is wondering how much popcorn and soda she should buy. Sigrur aims to buy a combination of both. She values her utility (utility is an economic measure of the mental benefits associated with a decision) of popcorn and soda with the following utility function: U (P,K)=6PK - P - K where P represents the amount of pop (100gr = 1) and K represents the amount of soda (100ml = 1) She has 800 krona to spend in the shop. Each 100 gr of popcorn costs 100 krona and each 100 ml of soda costs 75 krona. a) How much popcorn and soda should she buy in order to maximize her utility? b) When Sigrur stands at the counter, she finds an extra 200 krona in her pocket and decides to spend it all on more popcorn and soda. How much popcorn and soda is added to the original purchase? How much does her utility increase by having found this 200 krona?
