<h3>
Answer: A) 20+10h</h3>
Work Shown:
It grows 2h inches for 4 weeks, so 2h*4 = 2*4h = 8h is the amount it grows for those 4 weeks.
Then it grows h inches per week, for 2 more weeks, giving h+h = 2h additional inches.
Overall, 8h+2h = 10h is the amount the plant grows.
It starts off at 20 inches so its final height is 20+10h
Since the absolute value makes numbers absolute or real numbers you could replace the ? with 8/9 or -8/9 since the negative will go away because of the absolute value sign.
If you add all those #'s up you would get 72. The average money you need is $100 so you just subtract 100-72 and that would be your answer! :D
