Students in Ms. Alvarez's eighth grade science class are investigating how temperature, in degrees Celsius ("C), affects the solubility of a compound in
100 milliliters (mL) of water. Ms. Alvarez provides the students with a graph that
shows the solubility of a certain compound, as shown below.

She then tells the students that she will demonstrate how many grams (g) of the
compound will dissolve in 100 mL of water at 40°C. Based on the information in the
graph, which of the following is the best prediction of how many grams of the
compound will dissolve at 40°C?
