Question

A bank employee notices an abandoned checking account with a balance of $343. The bank charges an $7 monthly fee for the account. Write the equation that gives the balance F(x) in dollars as a function of the number of months x. (use F(x) in your answer)

Answer 1

F(x)=343-7x

Explanation:

let F(x) be the total amount on the account

and let x be the number of monthly charges

given that

c=$343

the monthly charge is =$7

The expression for the situation is

F(x)=c-mx

F(x)=343-7x

Therefore the expression for the balance is F(x)=343-7x
