Respuesta :
(9-5/5)*100= (4/5)*100 = 80% ( new height- original height /original height ) *100 the plant grew 80%
A week later, the plant grows by 80%.
What is percent change?
The percent change in value is given by,
percent change = (change in value/original value) × 100
For given situation,
Let 'h' represents the height of the plant.
On February 1st Amy's plant was 5 inches high.
⇒ original height (h) = 5 in.
A week later, the plant’s height became 9 inches high.
⇒ increase in height of the plant = 9 - 5
⇒ Δh = 4 in.
Using the formula for percent change in value the percent growth of plant would be,
⇒ percent change = (Δh/h) × 100
⇒ percent change = (4/5) × 100
⇒ percent change = 0.8 × 100
⇒ percent change = 80%
Therefore, a week later, the plant grows by 80%.
