Answer:
F = 25
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
Here V = 11, E = 34, thus
F + 11 - 34 = 2
F - 23 = 2 ( add 23 to both sides )
F = 25
How you do this problem is that you first find out how much the price has gone down.

Then, you divide 9.82 by the answer to your previous equation and then you have completed the question!
