The initial height is 8; the daily growth factor is 1+18% = 100%+18% = 118% = 1.18.
(a)
(b) # of days for the height to reach 27
The variable is in an exponent; use logarithms.
Or graph "8(1.18)^t" and "27" on a graphing calculator and see where the graphs intersect.
(c) # of days for the height to reach 149
Same as (b), just different numbers....
