Answer:

  21 miles

Step-by-step explanation:

Each of the distances is the same, so we have ...

  5x +4 = 15x -30

  34 = 10x

  3.4 = x

Then the distances are ...

  5(3.4) +4 = 21 . . . . miles

Bert and Ernie each live 21 miles from Big Bird's nest.

Find current interest:
=$2543.32 * 17.4%
=2543.32 * 0.174
=442.537

Add the interest to the current balance:
=2543.32 + 442.537
=2985.857

Add new transaction:
=2985.857 + 320
=3305.857 rounded to 3305.86

The answer is C) $3305.86

Answer:

  $189.32

Step-by-step explanation:

Add all of the numbers shown to the beginning balance to find the ending balance.

  $92.19 -39.35 +49.76 +87.35 +9.97 -10.60 = $189.32

Tristan's balance at the end of the month was $189.32.

__

There should be no confusion. Money deposited into the account increases the balance by the amount deposited.

Money spent from the account decreases the balance by the amount spent.

Here, amounts deposited are given a plus sign (+); amounts spent are given a minus sign (-).

__

<em>Additional comment</em>

It can be tedious to enter these numbers correctly into a calculator. Many folks prefer a calculator that provides a "tape", a record of the amounts and operations the calculator uses in the computation. Alternatively, you can put the numbers in a spreadsheet and use the SUM function to do the addition for you. That, too, makes it easy to check that numbers have been entered correctly.

The attachment shows the calculation done in a spreadsheet.
