Question

Julie's savings account has a balance of $57.85 in January. By March, her balance is 4 times as much as her January balance. Between March and November, Julie deposits a total of $78.45. If she does not withdraw any money from her account, what should Julie's balance be in November?

Answer 1

January . . . $57.85

March . . . . 4 times as much = 4 (57.85) = $231.40

Deposit 78.45 more . . . ($231.40 + 78.45) = $309.85 .

Notice that "interest" is never mentioned anywhere in this problem.
In other words, it doesn't matter whether Julie's savings account is
in a bucket in the basement, a mayonnaise jar on the porch, under
her mattress, or in a bank that pays no interest.

Without interest, $309.85 is what she does have in November, which
is about right for savings accounts in banks these days. i wish it help for all my hard work to answer the question.

March . . . . 4 times as much = 4 (57.85) = $231.40

Deposit 78.45 more . . . ($231.40 + 78.45) = $309.85 .

What her balance should be in November is an entirely different subject.
