Average Growth Rate Calculation for Fertilizers

Very Hard Data Representation Understanding Graphs And Tables

A group of researchers conducted an experiment to evaluate the effectiveness of two different fertilizers (Fertilizer A and Fertilizer B) on plant growth (measured in centimeters) over a 10-week period. The results were compiled into a table showing the average height of plants at the end of each week.

Below is a summary of the data collected:

Week	Fertilizer A (cm)	Fertilizer B (cm)
1	4	5
2	7	8
3	10	12
4	12	15
5	15	19
6	17	22
7	20	26
8	22	29
9	24	31
10	25	35

Based on the data presented in the table, what is the average growth rate per week for each fertilizer over the 10-week experimental period?

Fertilizer A: 2.5 cm/week, Fertilizer B: 3 cm/week

Fertilizer A: 1.7 cm/week, Fertilizer B: 2.5 cm/week

Fertilizer A: 1.2 cm/week, Fertilizer B: 2.8 cm/week

Fertilizer A: 2 cm/week, Fertilizer B: 2.8 cm/week
