Byron spends all his income on beer and peanuts. Byron's utility function is U(x, y) = min(4x, 2x + y) where x is his consumption of beer in cans and y is his consumption of peanuts in packets, and the function "min" means that the smaller number inside the parentheses is the utility. Byron is consuming 15 cans of beer and 10 packets of peanuts. The price of beer is $10 per can.
