Answer 1

[Find the changes in the salary]
Increase = 28100 - 25300 = 2800

[the change, divided by the original amount. x100 to give the percentage]
percentage increase = 2800/25300 x 100 = 11.07%

Answer 2

Increasing percentage = 11.06%.

Explanation:

Given : In 2015, Gary earned $25,300. In 2016, he received a raise and earned $28,100.

To find : what would be a good estimate for the percent increase.

Solution : We have given

In 2005 , Gray earned = $25,300.

In 2016, raise and earned = $28,100.

Increasing percentage =
`(increase\ value)/(orignal\ value)*100`.

Increased value = $28,100 -$25,300= $2800.

Increasing percentage =
`(2800)/(25300)*100`.

Increasing percentage =
`(2800)/(253)`.

Increasing percentage = 11.06%

Therefore,Increasing percentage = 11.06%.
