1. The problem states that the exchange rate graph shows the relationship between pounds (£) and Japanese yen (¥). 2. From the graph, the line passes through points (5, 750), (10, 1500), (15, 2250), and (20, 3000). 3. This indicates a linear relationship where every 1 pound corresponds to 150 yen because $\frac{750}{5} = 150$. 4. To find how much Bobby would receive for £70, multiply 70 by the exchange rate 150: $$70 \times 150 = 10500$$ 5. Therefore, Bobby would receive 10500 Japanese yen for £70.
