The scatterplot represents the relationship between the temperature outside and the number of ice cream cones sold. Predict how many ice cream cones would be sold if the temperature outside was 100°F.

• about 80 ice cream cones

• about 90 ice cream cones

• about 100 ice cream cones

• about 120 ice cream cones
