Explanation:
→ We want to calculate the percentage increase we saw in our premium.
→ To calculate the percentage increase we saw in our premium, let's calculate the difference between our first six-month car insurance premium and our renewal premium:
![\sf 786.25 - 629.00 = 157.25](https://img.qammunity.org/2023/formulas/mathematics/college/cu4weg9k4p1h7evpx0l7luort2lr7u678f.png)
→ Calculate the percentage:
→ The formula used to calculate the percentage is:
![\sf (value)/(total ~value) * 100\%](https://img.qammunity.org/2023/formulas/mathematics/college/9ir0xkwclhuofbj8lpgba0k8j2vy6wv5j4.png)
→ Apply this formula with value = 157.25 and total value = 629.00:
![\sf (157.25)/(629.00) *100\%](https://img.qammunity.org/2023/formulas/mathematics/college/n77qtyul9zx44ki6bt44uwwyjid4k3bau8.png)
→ Simplify the expression:
![\sf (157.25)/(629.00) *100\%\\\\\\= 0.25 *100\%\\\\\\= 0.25 * (100)/(100) \\\\\\= (0.25 * 100 )/(100) \\\\\\= (25)/(100) \\\\\\\boxed{\sf= 25\%}](https://img.qammunity.org/2023/formulas/mathematics/college/gchht1hs1xgezhfio6lloofya29qxwlazf.png)
Conclusion:
The percentage increase we saw in our premium is 25%.
