now we should focus on analysing the prices to alicante and to dublin. note that the departure city is berlin in all the cases. we can skip the evolution in prices to paris and also its price on the second chart, so we should mentally black out the corresponding row and column, as well as the columns for day -1 and day of travel, for the above-mentioned reason. last minute changes in air ticket price (compared to the price 5 days prior departure) day -5 day -4 day -3 day -2 berlin- 0% 5% 10% 15% alicante berlin- 0% -10% -10% -5% dublin berlin-alicante berlin-dublin price 5 days prior departure (gbp) 60 50 next, we observe that we have the initial prices for day -5 in gbp (by the way, the same currency that we need in the question, so not necessary to make currency exchange in this exercise, fortunately!). the initial prices are 60 for alicante and 50 for dublin. we can clearly see that on this day the difference in prices was 60 - 50 = 10 gbp, so this is not the target we are looking for, which is a difference of 15 gbp, according to the question's statement.
