8) Based on the estimate of TravelCo revenues and margins, what is correct to say?
(a) In terms of %, gross margins were the same in Y1 and Y3.
(b) Gross margins decreased 2% basis points between Y1 and Y2, mainly due to lower penetration of Domestic and LongHaul packages.
(c) TravelCo’s total sales are increasing approximately 5% per year on average between Y1 and Y5. However, total gross margins have not changed.
(d) TravelCo reached highest gross margins (in %) in Y1.
Anyone can explain why each one is wrong?
