Any help on any part of this question would be great!

Munira has the utility function U(cl,c2) = 311103) + 6 ln(c2) where c1 and c2 are her consumption in periods 1 and 2, respectively. She will earn $200 in period 1 and $220 in period 2. She can borrow or save at an interest rate of x and the price of the consumption good is $1 in each period. a. [2] Write Munira's present-value and future value budget constraints. b. [10] If Munira doesn't trust banks and decides to keep her savings in cash, solve for her optimal level of consumption in each period. Assume that she does not have access to other sources of credit. c. [10] While doom-scrolling spicy memes, Munira sees an attention grabbing advertisement about Ca$H Money-Mart and she decides to give financial intermediation a chance (i.e. she considers borrowing and saving at the prevailing interest rate). Solve for her optimal level of consumption in each period. What is the cut-off interest rate for Munira to become a saver? AZARIDIS )0! of Business 81 Economics d. [2] Are Munira's preferences consistent with discounting of her future consumption? Explain
