1. **State the problem:** We need to find the markup $M$ given the retail price $P$ and the wholesale cost $C$. 2. **Formula:** The retail price is given by $$P = C + M$$ where $P$ is the retail price, $C$ is the wholesale cost, and $M$ is the markup. 3. **Rearrange the formula to solve for $M$:** $$M = P - C$$ 4. **Substitute the given values:** $$M = 36 - 22$$ 5. **Calculate the markup:** $$M = 14$$ **Final answer:** The markup is **14**.
