money on only two goods‚ bananas and scones. Bananas cost $0.60/kg‚ and scones cost $0.50 each. a) (1) Sketch Rajan’s budget constraint if he has an income of $10.00/day. (Put bananas on the horizontal axis.) Ans: horizontal intercept = $10.00/$0.60=50/3; vertical intercept = $10/00/$0.50 = 20 must label axes ( deduct ½ mark if axes not labeled). Rajan has well-behaved preferences‚ and his optimal bundle contains 10 scones. b) (2) Illustrate his optimal bundle in your diagram for (a); label it

borax in water. “Borax” is a naturally occurring compound; it is in fact the most important source of the element boron‚ and it has been used for many years as a water softening agent. Borax is a rather complicated ionic salt which has the chemical formula Na2B4O7•10H2O (Petrucci‚ 2007). When it dissolves‚ it dissociates as follows: Na2B4O7 • 10H2O(s) 2Na(aq) + B4O5(OH)42(aq) + 8H2O(l) rnx (1) The solubility product expression for this system is written below. Ksp = [Na]2
