Robinson Crusoe receives utility from eating coconuts and fish. His utility function is U(C, F) = C + F, where C is units of coconuts and F is units of fish. If the price of coconuts is $10 and the price of fish is $1, what can you say about the bundle (combination of fish and coconuts) that maximizes Robinson's utility? (Note: you do not need to but you can make additional assumptions if it helps you answer the question).
