We can use the number line as a model to help us visualize adding and subtracting of signed integers. Just think of addition and subtraction as directions on the number line. There are also several rules and properties that define how to perform these basic operations.
To add integers having the same sign, keep the same sign and add the absolute value of each number.
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.
Subtract an integer by adding its opposite.

Answer:
$37,449
Step-by-step explanation:
<u>First convert 5% into a decimal</u>
.05
<u>Multiply the decimal by Alice's salary</u>
$39,420(.05)=1,971
<u>Now we subtract that answer from her salary this year</u>
$39,420-1,971=$37,449
<h3><u>
Alice's salary last year was $37,449</u></h3>
