2. A group of students conducted the bridge-thickness experiment with construction paper. The table below contains their results.

a. Make a graph of the (number of layers, breaking weight) data.
Describe the relationship between breaking weight and number
of layers.
b. Suppose it is possible to use half-layers of construction paper.
What breaking weight would you predict for a bridge 3.5 layers
thick? Explain.
c. Predict the breaking weight for a construction-paper bridge of
8 layers. Explain how you made your prediction.
