+# Hints
+
+## 1. Determine how long it takes to mix a juice
+
+- Julia has no `switch` statement, in contrast to many other languages.
+- The `if` ... `elsefif` ... `else` syntax was covered in the Conditionals concept.
+
+## 2. Replenish the lime wedge supply
+
+- A `while` loop can run until you have enough lime wedges.
+- The `popfirst!()` function was covered in the Vectors concept.
+
+## 3. List the times to mix each order in the queue
+
+- Looping over a vector is easy with `for` ... `in`.
+- Building a new vector could use `push!()`, which was covered in the Vectors concept.
+- Later in the syllabus we will explore various other ways to do this in Julia.
+
+## 4. Finish up the shift
+
+- See task 2.
