The x-axis is marked in whole units, from 0 to 12. The demand curve is marked at every half unit on the y-axis. Each half unit on the y-axis translates to two whole units on the x-axis (i.e. x=0 y=3.00, x=2 y=2.50, x=4 y=2.00, etc) Consider the figure above. Lowering price from $2.00 to $1.50 would
