The table shows the height of different plants, W, X, Y and Z grown in a room over a month.
Plant Height of plant at the start of the month Height of plant at the end of the month
W 110 cm 127 cm
X 116 cm 131 cm
Y 119 cm 132 cm
Z 118 cm 129 cm

Worked solution

1. Calculate the increase in height for plant W

Increase for W = $127 - 110 = 17$ cm

2. Calculate the increase in height for plant X

Increase for X = $131 - 116 = 15$ cm

3. Calculate the increase in height for plant Y

Increase for Y = $132 - 119 = 13$ cm

4. Calculate the increase in height for plant Z

Increase for Z = $129 - 118 = 11$ cm

5. Compare the increases to find the greatest

The increases are 17 cm, 15 cm, 13 cm, and 11 cm.
The greatest increase is 17 cm, which belongs to plant W.
