A florist arranged some flower bouquets. She sold 50% of the bouquets in the morning, 1/5 of the remaining bouquets in the afternoon, and had 36 bouquets left. How many bouquets did she arrange altogether?

Let the total number of bouquets the florist arranged be \( x \).

### Step-by-Step Solution

1. **Calculate bouquets sold in the morning:**  
   She sold 50% of the bouquets in the morning, so the number of bouquets sold in the morning is:
   \[
   \frac{1}{2} \times x = \frac{x}{2}
   \]

2. **Calculate remaining bouquets after the morning:**  
   After selling half of the bouquets, she had:
   \[
   x - \frac{x}{2} = \frac{x}{2}
   \]
   bouquets left.

3. **Calculate bouquets sold in the afternoon:**  
   In the afternoon, she sold \( \frac{1}{5} \) of the remaining bouquets:
   \[
   \frac{1}{5} \times \frac{x}{2} = \frac{x}{10}
   \]

4. **Calculate bouquets remaining after the afternoon:**  
   After the afternoon sales, the number of bouquets left was:
   \[
   \frac{x}{2} - \frac{x}{10} = \frac{5x - x}{10} = \frac{4x}{10} = \frac{2x}{5}
   \]

5. **Set up the equation with the given information:**  
   We are told she had 36 bouquets left, so:
   \[
   \frac{2x}{5} = 36
   \]

6. **Solve for \( x \):**
   Multiply both sides by 5 to eliminate the fraction:
   \[
   2x = 180
   \]
   Divide by 2:
   \[
   x = 90
   \]

### Answer
The florist arranged **90 bouquets** in total.
