(1 point) In the year 2001, a total of 7.9 million passengers took a cruise vacation. The global cruise industry has been growing at 9% per year for the last decade. Assume that this growth rate continues (a) Write a formula for to approximate the number, N, of cruise passengers (in millions) t years after 2001 Help on formulas. (b) How many cruise passengers (in millions) are predicted in the year 2012? E Help on numbers. (c) How many cruise passengers (in millions) were there in the year 2000? E Help on numbers.

Explanation / Answer

9% per year means factor is 1 +0.09 = 1.09

a)

N= 7.9 (1.09)^t

b)

Substitute t= 2012 -2001 = 11

N= 7.9 (1.09)^11

=20.4 millions

c)

Substitute t= 2000 -2001 = -1

N= 7.9 (1.09)^(-1)

=7.2 millions

All answeres are rounded to one decimal.
