Each month, Barry makes three transactions in his checking account.

Ostrovityanka [42]

Answer:

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

1.900+(n-1)150

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

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
