Answer:
square units
Step-by-step explanation:
To predict the area of the piece of paper after 5 tears we can use a geometric sequence.
Each time a piece is torn, half of the previous area is lost. If the area of the first piece is 1 square unit then:

square units
This can be done without exponential equations.
It doubles every 12 years so it has doubled in price
5,000 * 2 = 10,000
After 36 years the value has increased 8 times
5,000 * 8 = 40,000
After 48 years the value has increased 16 times
5,000 * 16 = 80,000
lions = x
monkeys = 3x ( 3 times as many )
3x +x = 24
4x = 24
x = 24/4
x = 6
6 lions
6*3 = 18 monkeys
