Amy is growing basil. On February 1st her plant was 5 inches high. A week later, the plant’s height became 9 inches high. By what percent did the plant grow?

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%.
