Harper wants to exchange £350 for dollars, how many more dollars would she get in the bank than in the post office post office: £1 = $1.27 Bank:£1 = $1.34

$24.50

Post office:£1 = $1.27

£350 = $1.27 × 350 = $444.50

Bank:£1 = $1.34

£350 = $1.34 × 350 = $469

Therefore, the difference will be:

= $469 - $444.50

= $24.50
