Question

for a science experiment, two plants, starting at different heights, are given different types of fertilizers. at the start of the experiment, plant 1 is 2 inches tall and grows at a rate of 1.5 inches per week. the table represents the height of plant 2.
plant 2s height

number of weeks	total height (in.)
1	5.5
2	7.5
3	9.5

at the start of the experiment, how much taller is plant 2 than plant 1?
a 3.5 inches
b 3 inches
c 2 inches
d 1.5 inches

Explanation:

Step1: Identify starting - heights

Plant 1 is 2 inches tall at start. From the table, Plant 2 is 3.5 inches tall at start (when number of weeks = 0).

Step2: Calculate the difference

Subtract the starting - height of Plant 1 from that of Plant 2. $3.5−2 = 1.5$.

Answer:

D. 1.5 inches
