Question

the height of a tree increases at the rate of 20% every year. If the present height of the tree is 28.8 meter, calculate the height of the tree 2 year before. ​

Answer 1

Answer:

20% of 28.8 meter = 5.76;

Now, 28.8 - 5.76 = 23.04;

height of tree before 1 year = 23.04 meter;

Now, 20% of 23.04 = 4.608;

Then; 23.04 - 4.608 = 18.432;

Now that's the final answere height of tree before 2 year is = 18.432 meter.
