Carley owns an ice cream stand. She wants to predict how many ice cream cones she will sell as a function of the average daily high temperature each month. The data for the past 777 months is shown in the table below. Jan Feb Mar Apr May Jun Jul

All of the scatter plots below display the data correctly, but which one of them displays the data best?
By convention, a good scatter plot uses a reasonable scale on both axes and puts the explanatory variable on the xxx-axis.

Graph A provides Average high temperature, in degrees Celsius, from 0 to 30, in increments of 5, on the y-axis versus Cones sold from 0 to 500, in increments of 50, on the x-axis. 7 points rise in a curve pattern with decreasing steepness from (0, 1) to (490, 27). There is a gap between x = 150 and x = 400. All values estimated.
~~~ space, space, space
Graph B provides Average high temperature, in degrees Celsius, from 0 to 90, in increments of 7.5, on the y-axis versus Cones sold from 0 to 1500, in increments of 150, on the x-axis. 7 points rise in a curve pattern with decreasing steepness from (0, 1) to (490, 27). There is a gap between x = 150 and x = 400. All values estimated.
Graph C provides Cones sold from 0 to 500, in increments of 50, on the y-axis versus Average high temperature, in degrees Celsius, from 0 to 30, in increments of 5, on the x-axis. 7 points rise in a curve pattern with increasing steepness from (1, 0) to (27, 490). There is a gap between x = 22 and x = 26. All values estimated.
