Question

Alec has a cherry tree in his yard. When he first planted it, the tree was 40 feet tall. Now it is 76 feet tall. What is the percent of increase in the height of the tree?

PLEASE HELP

Answer 1

90%

Explanation:

To find the percent of increase in the height of the tree, we need the change of the height and the original height (40 feet)

The change of height = 76 - 40 = 36 feet

Now, we need to divide the change by the original height to find the percent of increase.

36/40 = 9/10

9/10, which is then 90%.
