Question

A plant is already 12.00 meters tall and it will grow 20 cm every month.what is the plants height after 30 months

Answer 1

18 m

Explanation:

Hi there!

We're given:

⇒ The plant is already 12 m tall

⇒ It grows 20 cm every month

First, we must convert everything into the same unit. Divide 20 cm by 100 to convert it to meters:

20 ÷ 100 = 0.2

Now, we can form this equation:

Plant Height = 12 m + (0.2 m × number of months)

Let plant height be h and number of months be m:

`H=12+0.2m`

To find the plant's height after 30 months, replace m with 30:

`H=12+0.2(30)\\H=12+6\\H=18`

Therefore, the plant would be 18 m tall.

I hope this helps!
