Answer:
After 12 years both will be in same height
Step-by-step explanation:
Let 'x' be the number of years .
After 'x' years both will be in same height
Genevieve:
Rate of growth per year = 1.5 ft
Rate of growth after 'x' years = 1.5 * x = 1.5x
Height of tree after 'x' years = 3 + 1.5x
Marcus:
Rate of growth per year =1.75 ft
Rate of growth after 'x' years = 1.75 * x = 1.75x
Height of tree after 'x' years = 1.75x
After 'x' years both will be in same height
1.75x = 3 + 1.5x
1.75x - 1.5x = 3
0.25x = 3
x = [tex]\frac{3}{0.25}[/tex]
[tex]x =\frac{3*100}{0.25*100}=\frac{300}{25}[/tex]
x = 12
