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

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

$\frac{106.7}{100} * x = 28.5$

$\frac{106.7x}{100} = 28.5$

Multiply both sides by 100

$\frac{106.7x}{100} * 100 = 28.5*100$

$106.7x = 2850$

Divide both sides by 106.7

$\frac{106.7x}{106.7} = \frac{2850}{106.7}$

$x = 26.7$ (approximated)

Number of passengers in 2017 must have been approximately 26.7 million
