Jamal is testing the effect of a plant fertilizer for his science fair project. One plant is 12 centimeters tall and grows 1.2 centimeters per day. Another plant is 8 centimeters tall and grows 1.7 centimeters per day. After how many weeks will the plants be the same height?

Answer :

Final answer:

The plants will be the same height after 8 days, or 1 week.

Explanation:

The student is testing the effect of a plant fertilizer on plant growth. One plant is 12 centimeters tall and grows 1.2 centimeters per day, while another plant is 8 centimeters tall and grows 1.7 centimeters per day. To find out when the plants will be the same height, we can set up a comparison equation:

12 + 1.2x = 8 + 1.7x

Simplifying the equation, we get:

1.2x - 1.7x = 8 - 12

-0.5x = -4

x = 8

Therefore, the plants will be the same height after 8 days, or 1 week.
