Mark spent $80 to buy 10 cans of beer (good X) and 5 bottles of wine (good Y) last week. Each can of beer cost Px and each bottle of wine cost Py. Suppose he is a utility maximizing agent.
1. Now, the price of one bottle of beer has increased by $1 and he has spent the same amount of money to buy 8 cans of beer and 5 bottles of wine. Find the price of beer before the change and the price of wine.
2. What is the MRS before the price change and after the price change?
