the tree would be 40 feet tall in 15 years.
1. 72 to 50 points
50/72 = 69%
100-69= 31% decrease
2. 14 to 40 books
14 / 40 = 35%
100-35= 65% increase
3. 10 plus 30% increase
10 * 0.3 = 13
Answer:
the width is ≤ 38 feet

the perimeter of a rectangle is given by the relation : 2*( length + width)
P ≤ 120
2 (L + W) ≤ 120
L + W ≤ 60 ,,, L = 22
22 + W ≤ 60
W ≤ 38 feet
