Question

Today, after 10 days, the bean plant is 27 inches tall. How tall was it yesterday?

Answer 1

23.48 in

Explanation:

27 inches divided by 1.15 is equal to how tall the bean plant was yesterday.

Answer:

27/1.15= 23.48 inches

Answer 2

23.48 inches

Explanation:

Knowing that the plant grows 15% of its height every day, 27 inches would represent 115% of its height from the day before.

To find how it was yesterday, simply divide 27 inches by 115% (or 1.15).

27 inches/1.15 = 23.48 inches
