1. The problem is to convert £250 into dollars using two different exchange rates: £1 = $1.27 and £1 = $1.36. 2. The formula to convert pounds to dollars is: $$\text{dollars} = \text{pounds} \times \text{exchange rate}$$ 3. First, calculate the amount in dollars using the post office rate: $$250 \times 1.27 = 317.5$$ 4. Next, calculate the amount in dollars using the travel agent rate: $$250 \times 1.36 = 340$$ 5. So, £250 is equivalent to $317.5 at the post office and $340 at the travel agent. This shows how different exchange rates affect the amount of money received when converting currencies.
