The document contains calculations of total revenue (TR), average revenue (AR), and marginal revenue (MR) at different levels of quantity (Q) sold from 1 to 15 units. TR increases as Q increases from 1 to 7, then decreases as Q increases from 8 to 15. AR decreases as Q increases from 1 to 15. MR decreases as Q increases from 1 to 7, then becomes negative and decreases further as Q increases from 8 to 15, reaching its lowest point at -900 before increasing again to 0.
