below. Suppose that the price of X is $4 (Px - $4). the price of Y is $5 (Py = $5), and goods X and Y are infinitely divisible (i.e., good X can be purchased in fractions of a unit such as a 1/4 of a pound of ground beef or 1/100 of a gallon of gas). Suppose that Max's income is $220 and he buys 30 units of X and 20 units of Y. If Max buys $1's worth less of good X and $1's worth more of good Y, then his total utility will Qx MUx Qy MUY 20 128 15 240 21 112 16 210 22 96 17 180 23 88 18 160 24 80 19 140 25 72 20 120 26 64 21 100 27 56 22 80 28 52 23 70 29 48 24 60 30 44 25 50 31 40 26 40 O decrease by 10 utils. increase by 13 utils. increase by 10 utils.
