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.

[tex]S(t)=22.52(1.125)^{t}[/tex]

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

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

[tex]S(t)=22.52(1.125)^{14}=117.1[/tex]

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

[tex]S(t)=22.52(1.125)^{18}=187.6[/tex]
