Question

According to the same report, the 28.5 million passengers in 2018 represented a 6.7% increase in cruise passengers since 2017. How many cruise passengers must there have been in 2017

Answer 1

approximately 26.7 million

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

`(106.7)/(100) * x = 28.5`

`(106.7x)/(100) = 28.5`

Multiply both sides by 100

`(106.7x)/(100) * 100 = 28.5*100`

`106.7x = 2850`

Divide both sides by 106.7

`(106.7x)/(106.7) = (2850)/(106.7)`

`x = 26.7` (approximated)

Number of passengers in 2017 must have been approximately 26.7 million
