Question

Chris plants a sunflower that is 6 inches tall. The sunflower is expected to grow at an average rate of 1.5 inches per day during the next month.

A. Create an equation that Chris can use to find the number of days, x, it will take the sunflower to grow to a height of 45 inches.


B. How many days will it take the sunflower to grow to a height of 45 inches?

Answer 1

A. The equation that represents this scenario would be 6 + 1.5d = 45. The reason is that the plant starts out at 6 inches(6) and (+) grows 1.5 inches each day (1.5d).

B. We will solve the equation to find out how many days it will take to get to 45 inches.

6 + 1.5d = 45
-6 -6
1.5d = 39
1.5 1.5
d = 26

The number of days it would take is 26.
