1. **State the problem:** Tony's total holiday costs include flights, hotel, wifi, and taxi journeys. We need to find the total cost in pounds (£). 2. **Given data:** - Flights cost £1600 - Hotel cost $175 per night for 12 nights - Wifi cost $7 per day for 10 days - Taxi cost $28 per journey for 6 journeys - Exchange rate: $1.79 = £1 3. **Calculate hotel cost in dollars:** $$175 \times 12 = 2100$$ dollars 4. **Calculate wifi cost in dollars:** $$7 \times 10 = 70$$ dollars 5. **Calculate taxi cost in dollars:** $$28 \times 6 = 168$$ dollars 6. **Calculate total cost in dollars (excluding flights):** $$2100 + 70 + 168 = 2338$$ dollars 7. **Convert total dollars to pounds:** Since $1.79 = £1$, then $$\text{pounds} = \frac{\text{dollars}}{1.79}$$ So, $$\frac{2338}{1.79} \approx 1306.15$$ pounds 8. **Add flight cost in pounds:** $$1600 + 1306.15 = 2906.15$$ pounds **Final answer:** Tony's total holiday cost is approximately **£2906.15**.
