solution: After Kathy has exchanged half of her money ($300\text{ USD}\div 2 = 150\text{ USD}$) into pounds, she will have $150\text{ USD}\times\frac{1\text{ pound}}{1.64 \text{ USD}}\approx 91.46 \text{ pounds}$. After exchanging the other half of her money into euros, she will have $150\text{ USD} \times\frac{1\text{ euro}}{1.32 \text{ USD}}\approx 113.64\text{ euros}$. Subtracting these two values, we have $113.64-91.46=22.18$. Since the question calls for the nearest whole number, we round 22.18 to the final answer of $\boxed{22}$.
