How much charlie will save as function of the interest rate

Charlie cares only about the amount of chocolate he eats this year (C0) and next year (C1). His preferences correspond to the utility function $U(C_{0},C_{1})=4(\sqrt{C_{0}}+\sqrt{C_{1}})$ Suppose he earns $1,000 this year and nothing next year. Chocolate costs $1 per ounce this year and $4 per ounce next year.

A) Assume the interest rate is 10% (or 0.10). What is Charlie's optimal bundle?

B) Provide a graph of this solution.

C) Now suppose the interest rate (expressed as a decimal) is R. Find a general formula showing how much Charlie will save as a function of the interest rate.

D) When the interest rate rises, does Charlie save more or less? How do you know
