He deposits $700 from his paycheck.
He withdraws $150 to buy gas for his car.
He withdraws $400 for other expenses.
If his account balance is $1,900 at the end of the 1st month, which recursive equation models Barry's account balance at the end of month n?

Answer:

The recursive equation that models Barry's account balance is equal to

1.900+(n-1)150

or

150n+1,750

Step-by-step explanation:

Let

n -----> the number of months

f(n) -----> Barry's account balance

we know that

700-150-400=$150

so

The recursive equation that models Barry's account balance is equal to

f(n)=1,900+(n-1)150

f(n)=1,900+150n-150

f(n)=150n+1,750

Answer:   For plato family

D.   f (1) =  1900

      f(n) = f (n - 1) + 150  ,for n > 2
