Andrei loves to bake, and plum tarts are his specialty. Plums are on sale for $\$3.25$ for $2$ pounds at the farmer's market. At the supermarket, plums are being sold according to the following equation, where $P$ is price in dollars and $L$ is pounds: $P=1.75L$. **Where do plums cost less, at the farmer's market or the supermarket?**
