Could I have an explanation by letter, I don't understand

Exercise 3 Consider a two period model1 populated by a representative consumer and a govern- ment. The consumer's preferences can be described by the utility function: \"(00:61): 711 + 6%. where f? = 0.95 captures the consumer's preference for the future. The consumer has an income yn=2 in the current period and expect a future income y1 = 25. The government plans to spend Ga = 5 in the current period and 01 = T. The interest rate is r = 1D% in the economy. (a) If the government decides to impose a tax of Ta = 7', what will be the value of T1? {b} Is it optimal for the consumer to consume his disposable income in each period? Explain. {c} Solve the consumer's problem and nd the optimal consumption in each period when r = 10%. Is the consumer a borrower or a lender? (d) Is the goods market in the equilibrium in the two periods when r = 10%? Explain. {e} What are the equilibrium values of (c0, c1] using goods market equilibrium? (f) Compute the equilibrium interest rate -r'*. {g} What would happen to the equilibrium interest rate if the government were to raise its expenditures in the future? (h) In the equilibrium1 which income stream is more benecial for the consumer, the initial one we started with or yo = 25 and y1 = 20
