Question

A rose bush of height `h` is planted at an initial height of 3 feet. The bush is expected to grow an average of 0.5 feet per year. How tall will the bush be 3 years after planting? Show the work that leads to your answer (either in the text box below or on the white board to the right).

Answer 1

Answer:

The height is 4.5ft

Step-by-step explanation:

Given

$Initial\ Height = 3\ ft$

$Growth = 0.5\ ft$ yearly

Required

Determine the height in 3 years

First, we need to determine the growth equation.

Represent the height with h and the years with x

So:

$y = Initial\ Height + Growth * x$

$y = 3 + 0.5 * x$

$y = 3 + 0.5x$

To solve the required, we have that:

$x = 3$

$y = 3 + 0.5x$ becomes

$y = 3 + 0.5 *3$

$y = 3 + 1.5$

$y = 4.5$

Hence, the height is 4.5ft
