Question

Isabella is seeding plants. She seeds 6 plants every hour, and she has already seeded 20 plants. Which of the following represents the number of plants y seeded after x hours?

y=6+20x

y=20+x

y=6+6x

y=20+6x

Answer 1

To determine the equation that represents the number of plants \( y \) seeded after \( x \) hours, we can analyze the information given:

1. Isabella has already seeded 20 plants.
2. She seeds an additional 6 plants every hour.

The equation needs to reflect both the initial 20 plants and the additional plants seeded over time.

After \( x \) hours, the number of additional plants seeded would be \( 6x \). Therefore, the total number of plants seeded \( y \) is given by the initial number of plants (20) plus the additional plants seeded after \( x \) hours (which is \( 6x \)).

So the correct equation is:

\[
y = 20 + 6x
\]

Thus, the answer is:

**y = 20 + 6x**
