Calculate the difference in Pedro's ownership in the following scenarios: Superthing raised its A round at 1.50 per share. Pedro invested 1.5 million for one million shares and 30 percent ownership. Now Superthing is raising a B round, but the market has turned against it and Rhul will pay only 1.00 per share for 1 million shares. (Assume that Pedro doesn't participate at all and allows Rhul Ventures to take the whole round.)

a. What if Pedro has full-ratchet antidilution?

b. Weighted average?
