Given:
height at 60 days old - 195cm
height after 60 days old - 2.5cm per day
total height = 195 cm + 2.5cm(x - 60)
x = day measured
22 days old
total height = 195cm + 2.5cm(22-60)
t.h = 195cm + 2.5cm(-38)
t.h = 195cm - 95cm
t.h = 100 cm
82 days old
total height = 195cm + 2.5cm(x-60)
t.h = 195cm + 2.5cm(82-60)
t.h = 195cm + 2.5cm(22)
t.h = 195cm + 55cm
t.h = 250cm
