550 GBP x 1.18 Euro = 649 Euro

649 - 629 = 20 Euro

1GBP x 20 Euro / 1.18 Euro = 16.94 Euro
Correct number, wrong units.

To find the commission in GBP, use the exchange rate to convert the Euros which she received to GBP and subtract that from the amount of GBP she changed.

= £550 - €629/(1.18 €/£)
= £16.95
