Final answer:
To find the smallest amount of money that Robyn could have converted, we compare the exchange rates for pounds to euros in two different airports and calculate the amount of pounds based on the lowest exchange rate.
Step-by-step explanation:
To find the smallest amount of money that Robyn could have converted, we need to determine the lowest exchange rate between pounds and euros from the given data. Let's compare the exchange rates for pounds to euros in the two different airports:
- Airport A: 1 pound = 1.21 euros
- Airport B: 1 pound = 1.17 euros
Since Robyn received 68.31 euros, we need to find the highest possible value for the pounds she converted. If she used the lowest exchange rate of 1.17 euros per pound (from Airport B), the formula to calculate the amount of pounds would be: pounds = euros / exchange rate = 68.31 / 1.17 = 58.41 pounds. Therefore, the smallest amount of money that Robyn could have converted is 58.41 pounds.
