You can put this solution on YOUR website!
The plant's height is given by
h+=+8+%2B+0.8w where h is hte height and w is the number of weeks
You are asked to say when plant will be taller than 13.6cm
13.6+%3C+8+%2B+0.8w
5.6+%3C+0.8w
5.6+%2F+0.8+%3C+w+
7+%3C+w
So anytime after 7 weeks, gets the job done!
