Ik dis this is really hard to do but plz try to me : )

(a) The breaking strength is 10 times the number of layers;

(b) 35 pennies; (c) 80 pennies.

Step-by-step explanation:

(a) The graph

I plotted the graph in the diagram below. It looks roughly the same as yours.

It looks like the breaking strength goes up another 10 pennies each time you add a layer.

Saying it another way, the breaking strength is 10 times the number of layers.

(b) Breaking strength of 3.5 layers.

The breaking strength is 10 times the number of layers.

If we have 3.5 layers, the breaking strength should be

10 × 3.5 = 35 pennies

See the red point labelled B on the graph.

(c) Breaking strength of eight layers.

The breaking strength is 10 times the number of layers.

If we have 8 layers, the breaking strength should be

10 × 8 = 80 pennies

See the orange point labelled C on the graph.
