Lin is tracking the progress of her plant’s growth. Today the plant is 5 cm high. The plant grows 1.5 cm per day.
Will there be a day where she will measure the plant at 112 inches tall?
Will there be a day where she will measure the plant at 112 inches tall?
a)
Yes, when the plant is 25 days old.
b)
Yes, when the plant is 100 days old.
c)
No because when I use y=112, the resulting x value is not a whole number. That length will fall between 71 and 72 days.
d)
The plant will never get that tall.
