ah okay, I can see how you may have thought that. As the promotion is for 80% off return flights, you would also need an outbound ticket to then have a return ticket. As the friends haven't travelled yet, it's safe to presume the friend is joining them for the whole trip.
@@AssessmentDayLtd 5 th friend is joining them for the whole trip.. if this is correct then the total fare will be 5*80 (inbound) = 400 5*80 (*0.2 -80 %) discount . 480 .. why are we calculating for 4 friends when 5 are traveling.. 800 is the total fare (5 friends inbound and outbound).. return flight = 80.. 480/800 = 0.6 - 1 = 40% so they saved 320 no.. or did i get the question wrong?

Wait, wait .... so many questions... First, what is the original fare? Only if the 4 friends went together or if the 5 friends went together without the discount offer? Second, where does the 5th friend come from? Are they doing a two-way travel or do the 4 friends pick them up from the Isle of Man? All of these questions do not allow you to give a definite answer since they are not specified as required information in the math problem.
When you are calculating percentage decrease, 80% becomes 0.2 as a decimal (100 - 80 = 20 / 100). And so, when you are calculating a percentage decrease of 80%, you do not multiply by 0.8, but rather, by 0.2, as multiplying by 0.8 would give you a percentage of 80%, which is not the question.
Let's assume that you are told to calculate a percentage decrease of 45% from 50. You will minus 45 from 100 (55), divide 55 by 100 (0.55). The calculation will be 50 x 0.55 = 27.5.
