Question

A tree is 4.1 feet tall. It is expected to grow by 14 feet per year.

At this growth rate, how many years will it take for the tree to have a height greater than 40 feet Enter the answer in th

Answer 1

It will take 3 years.

Explanation:

To solve, we need the equation:

4.1+14x > 40.

x represents the number of years.

Then plug in numbers till we get above 40.

4.1+14(1) > 40.

4.1+14 > 40.

16.1 > 40.(incorrect)

4.1+14(2) > 40.

4.1+28 > 40.

32.1 > 40.(incorrect)

4.1+14(3) > 40.

4.1+42 > 40.

46.1 > 40.(correct)

I hope this helps!

Answer 2

3 Years.

Explanation:

4.1 feet = Starting Height.

4.1 + 14 feet = 18.1 feet.

18.1 + 14 feet = 32.1 feet

32.1 + 14 feet = 46.1

Count the number of times you added 14 to your number.

1, 2, 3.

It would take 3 years for the tree to have a height greater than 40 feet.
