Answer:
The balance of card is 20.
Step-by-step explanation:
The given function is
[tex]y=2000(0.25)^{x-1}+20[/tex]
Where, the value of y represents the balance of card in x months.
We have to find the balance of the card in 24 months.
Put x=24 in the given function.
[tex]y=2000(0.25)^{24-1}+20[/tex]
[tex]y=2000(0.25)^{23}+20[/tex]
[tex]y=20[/tex]
Therefore the balance of card is 20.
