Answer:
Percentage increase in the height is 55%.
Step-by-step explanation:
Since Cindy is growing plants for a science project. During the project Cindy found that one plant grows from 7 cm to 10.85 cm.
We have calculate percent increase in the height of the plant.
We know formula to calculate the percentage is
% Increase in the height = Net increase in the height×100/Initial length of the plant
= 
Therefore % increase in the height of the plant is 55%.
20% is equal to 0.2
0.2 times 26.40 is equal to 5.28
26.40 minus 5.28 is equal to 21.12
10cm is the same as point 1 meter so 1.6 minus point 1 is 1.5
