My question is related to health economics and the correlation that exist between the demand curve and coinsurance at different rates.

Here is the question:

Show the impact on a demand curve of coinsurance. Show this for varying rates of coinsurance (10-90 vs 20-80 vs 50-50).

P.S. I need a graph !!!!

Thank you
