Answer:
approximately 26.7 million
Step-by-step explanation:
Let x be the number of cruise passengers in 2017.
6.7% increase of x gives us 28.5 m cruise passengers in 2018.
Thus, 106.7 % of x = 28.5
Multiply both sides by 100
Divide both sides by 106.7
(approximated)
Number of passengers in 2017 must have been approximately 26.7 million
