Question

Sandra started her job with a salary of 27,500. She received a 10% raise at the beginning of the next year. What is her salary for the 2nd year?

Answer 1

`27500 * 1.10 = 30250`

Answer 2

$30,250

Explanation:

Step 1: Find out what 10% of $27,500 is

First, change 10% to the decimal equivalent of 0.1 (divide 10 by 100)

Step 2: Multiply $27,500 by 0.1

$27,500(0.1) = $2,750

Her raise was $27,50

Step 3: Add her raise to her salary

$27,500 + $2,750 = $30,250,

This is her salary for year 2.

*A shortcut when multiplying with percent is to look at it as, in the second year, she is making 100% of her previous salary, plus 10% including the raise, so she's making 110% of what she used to.

Change 110% to a decimal by diving by 100.

110/100 = 1.1

Now multiply $27,500 by 1.1

$27,500(1.1) = $30,250
