Question: Jaylen is picking berries. The number of blueberries he picks is 4 less than half the number of strawberries he picks.
If Jaylen picks $x$ strawberries, select the expression that represents the number of blueberries he picks.
$x/2 - 4$
$2x + 4$
$x/2 + 4$
$x/4 + 2$
1. **State the problem:** Jaylen picks $x$ strawberries. The number of blueberries he picks is 4 less than half the number of strawberries.
2. **Write the expression:** Half the number of strawberries is $\frac{x}{2}$.
3. Since the blueberries are 4 less than half the strawberries, subtract 4:
$$\frac{x}{2} - 4$$
4. This matches the first option: $x/2 - 4$.
**Final answer:** $\boxed{\frac{x}{2} - 4}$
