On the other hand, his marginal utility per doughnutis 10 for the first doughnut he eats, 9 for the second he eats,8 for the third he eats, and so on (that is, declining by 1 utilper additional doughnut). In addition, suppose that coffeecosts $1 per cup, doughnuts cost$1 each, and Omar has abudget that he can spend only on doughnuts, coffee, or both.How big would that budget have to be before he wouldspend a dollar buying a first cup of coffee
