Answer
210 pounds
Explanation
First, we are going to find the exchange rate from dollars to pounds.
We know form our problem that 800 dollars are 560 pounds. so:
\(\frac{560pounds}{800dollars} =0.7\) pounds per dollar.
Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:
\(300dollars*\frac{0.7pounds}{dollar} =210pounds\)
We will get 210 pounds for 300 dollars
