Corollary 2.1
WholesalePrice (ProductX in BundleY)
= RetailPrice (BundleY) * MarginalChurnContribution (ProductX in Population of BundleY)
Corollary 2.2:
The best bundling outcome will have:
WholesalePrice (ProductX in BundleY) = RetailPrice (ProductX)
* SuperFan% (ProductX in Population of BundleY)
The bundle is "optimal" when:
RetailPrice (BundleY) * MarginalChurnContribution (ProductX in Population of BundleY)
= RetailPrice (ProductX) * SuperFan% (ProductX in Population of BundleY)
