Question

Two plants, labeled A and B, are both 3 centimeters in height. One month later, plant A is 7 centimeters taller. Plant B is half as tall as plant A. How tall is plant B?

Answer 1

The answer is D "What is the Current Height of plant B?"

Explanation:

Answer 2

For this case, we have initially both plants are 3 cm tall.

If a month later the plant A is 7 cm higher, it means that its height will be:

`A = 3 + 7 = 10 \ cm`

If they tell us that plant B is half the height of plant A, that means:

`B = \frac {10} {2} = 5`

Answer:

5 centimeters
