6. The interest rate is 10%, and y = (600, 200). The total utility function is max V (c1, C2) = In(c1) + In(c2) C1, C2 The optimal consumption bundle c = (c1, C2) is approximately a. (391,430) b. (600,200) c. (500,310) d. (400,400)4. A consumer faces y = (yl,y2) = (5,11), and a real interest rate of 10%. Which of the following consumption bundles satisfy the consumer's intertemporal budget constraint? 3. c1 = 6, c2 = 10 b. c1 = 4,c2 = 12.5 c. c1 = 16.5, c2 = 0 d. c1 = 0,c2 = 16.5
