A small-scale garment factory operates in the short run with a fixed quantity of equipment and variable labor ($L$). When $3$ tailors are employed, total output ($TP$) is $45$ shirts per day. When $4$ tailors are employed, total output rises to $64$ shirts per day, and when $5$ tailors are employed, total output reaches $75$ shirts per day. What is the marginal product ($MP$) of the $5\text{th}$ tailor?
