And bull What would be the effect on the company's overall net operating income if product XRAY were dropped?

If product XRAY were dropped, the company's overall net operating income would likely decrease if XRAY contributes positively to the income. This is because the fixed costs associated with the product would still need to be covered, and any contribution margin from XRAY would be lost. Conversely, if XRAY is operating at a loss, dropping it could improve net operating income by eliminating that loss, but it would also mean losing any potential revenue. The overall effect depends on XRAY's profitability and its impact on the company's fixed and variable costs.
