Stacy's lifelong dream is to meet Lady Gaga in person. After seeing her in concert, she is 100% certain this dream will come true, but for every year that she does not see her live in concert, she is half as sure that it will
really happen. Come up with a function that describes the yearly decay of Stacy's lifelong dream.
Let t = the number of years that have passed without her seeing Lady Gaga in concert and D = the percent
of certainty that her dream will come true.
A. D(t) = 100(1.5)^t
B. D(t) = 100(.5)^t
C. D(t) = 1/2t• 100
D. D(t) =100/2t
