Answer:
Total increase in height is 31.04 %
Step-by-step explanation:Let initial height be x.
Height increased last year= 17% of x = 0.17x
so last year height = x +0.17x = 1.17x
Height increased this year = 12%
so increase in this year height = 12% of 1.17x = (0.12)(1.17x)
= 0.1404x
Height of this year = 0.1404x +1.17x = 1.3104x
total increase = 1.3104x - x = 0.3104x
% increase = [tex]\frac{increase }{initial} (100)[/tex]
= [tex]\frac{0.3104x}{x} (100)[/tex]
= 31.04
