Jack has 3 boxes of pencils with the same number of pencils in each box. His mother gives him 4 more pencils. now jack has 28 pencils. How many pencils are in each box?

Answers

Here is the answer to the question above. Given that Jack has 3 boxes of pencils with the same number of pencils in each box. Since he has now 28 pencils all in all because his mother gave him 4, therefore, the original number of pencils he has is 24. Since he has 3 boxes, 24 divided by 3 is 8. Therefore, each box has 8 pencils. Hope this helps.

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?

Answers

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.

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

January . . . $57.85

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

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