Percent increase is a percent change that describes an increase in quantity
To determine percent increase we first find the amount of change
It is given:A tree grew from 4ft to 12ft in 3 years .
Amount of change =12-4=8 ft.
We use proportion to find percent increase.

Or ,
Cross multiplying we have:
4 ( percent Increase )= 800
Dividing by 4 we have Percent change = 200
Percent Increase = 200%.
a. 20 because y is the amount of $$ in account now
b. 12 a $$

Answer:
AED 15,000
Step-by-step explanation:
Depreciation is a reduction in the value or worth of an asset as a result of use.
Given that the car is depreciated by 20%, it means that the value of the car after the application of depreciation is the result of the original price of the car less the amount of depreciation which has been given as 20% of the original price.
Let the original price of the car (its price when it was new) be T then
T - 0.2T = 12,000
0.8T = 12,000
T = 12,000/0.8
= AED 15,000
