1. **Stating the problem:** We need to complete the table showing the number of web shops in the Netherlands for the years 2019, 2020, and 2021, given some percentage increases and known values. 2. **Given data:** - In 2020, there were 58 thousand web shops. - From 2019 to 2020, the number increased by 35%. - From 2020 to 2021, the number increased by 24%. 3. **Find the number of web shops in 2019:** Let the number of web shops in 2019 be $x$ thousand. Since the number increased by 35% from 2019 to 2020, we have: $$58 = x + 0.35x = 1.35x$$ 4. **Solve for $x$:** $$x = \frac{58}{1.35}$$ 5. **Simplify the fraction:** $$x = \frac{\cancel{58}}{\cancel{1.35}} \approx 42.96$$ So, in 2019, there were approximately 42.96 thousand web shops. 6. **Find the number of web shops in 2021:** The number increased by 24% from 2020 to 2021, so: $$\text{2021 amount} = 58 + 0.24 \times 58 = 1.24 \times 58$$ 7. **Calculate:** $$1.24 \times 58 = 71.92$$ So, in 2021, there were approximately 71.92 thousand web shops. 8. **Complete the table:** | year | 2019 | 2020 | 2021 | |-------|-------|-------|-------| | amount (× 1000) | 42.96 | 58 | 71.92 | **Final answer:** - 2019: 42.96 thousand - 2020: 58 thousand - 2021: 71.92 thousand
