Chapter 1.5, Problem 41E

To determine

To explain: $\text{The expression -25 +108 +(-20) represents the new balance and whether it is positive or negative}\text{.}$

Answer to Problem 41E

  $\text{ The new balance is 63 and it is positive}\text{.}$

Explanation of Solution

Given information:

The account shows an overdraft. $\text{The present balance is -\$25}\text{.}$

  $\text{Amount deposited = \$108}\text{.}$

  $\text{Amount withdrawn = \$20}\text{.}$

As per the question;

  $\text{The present balance is an overdraft therefore is shown by negative sign as -\$25}\text{.}$

  $\text{The money deposited is shown as +\$108}\text{.}$

  $\text{The withdrawal of money is shown by negative sign as -\$20}\text{.}$

The new balance can be written as:

  $\text{-25 + 108 +(-20)}$

Evaluating the expression;

  $\text{-25 + 108 =83}$ ;

  $83+(-20)=63.$

Hence;

The new balance is positive.
