Question

What is the approximate value of the expression:

$$5.03\% 	ext{ of } 39.89 + 10.09\% 	ext{ of } 450 = ?$$

Accepted Answer

**Solution:**

1. To simplify the calculation, approximate the percentages and numbers:
   - $5.03\%$ of $39.89$ is approximately $5\%$ of $40$.
   - $10.09\%$ of $450$ is approximately $10\%$ of $450$.

2. Calculate each part:
   - $5\%$ of $40 = \frac{5}{100} 	imes 40 = 2$
   - $10\%$ of $450 = \frac{10}{100} 	imes 450 = 45$

3. Add the two results:
   $$2 + 45 = 47$$

**Answer:** $47$
