1. **State the problem:** Liam's weekly train fare has increased by 8%, and he now pays an extra 2.20 every week. We need to find his new weekly train fare. 2. **Identify the variables:** - Let the original weekly fare be $x$. - The increase is 8% of $x$, which equals 2.20. 3. **Write the equation:** $$0.08x = 2.20$$ 4. **Solve for $x$:** $$x = \frac{2.20}{0.08} = 27.5$$ 5. **Find the new fare:** The new fare is the original fare plus the increase: $$27.5 + 2.20 = 29.7$$ 6. **Answer:** Liam's weekly train fare now is **29.7**.
