The "40 percent" figure is highly misleading. Funding for the Affordable Care Act comes from a tax on households earning more than $250,000 per year (or individuals earning more than $200,000 per year). That represents about 3% of the US households, not 40%.

This emphasizes that the Republican health care plan is really at heart just a tax cut for the wealthy, funded by taking away health care from middle and low income households.
