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
