. Sofia had planned to exchange £300 for euros during a visit to the local town one Saturday.
She had checked the exchange rate for that day, and found it to be £1 = 1.20 euros.
Unfortunately, she had to cancel her visit to town that day, and it was not until the following
Saturday that she was able to exchange her £300 for euros.
By this date the exchange rate was £1 = 1.17 euros.
How many fewer euros did she receive due to this delay?
What percentage loss was caused by this delay? [4]
