Question

Sales The sales S (in billions of dollars) for walgreens from 2000 through 2010 can be modeled by the exponential function

Answer 1

Answer:

(a) 117.1 billions of dollars

(b) 187.6 billions of dollars

Step-by-step explanation:

The sales S (in billions of dollars) for walgreens from 2000 through 2010 can be modeled by the exponential function.

$S(t)=22.52(1.125)^{t}$

where t is the time in years, with t = 0 corresponding to 2000.

(a) In 2014, t = 2014 - 2000 = 14

$S(t)=22.52(1.125)^{14}=117.1$

(b) In 2018, t = 2018 - 2000 = 18

$S(t)=22.52(1.125)^{18}=187.6$
