Mr. dawkins earn $550 a week until he receive a raise. after the raise, he earned $566.50 by what percent did mr. dawkins’ salary increase?

Hello!

The formula for percentage increase is:

Percent Increase = {( New Value - Old Value) / Old Value × 100}

Substitute = {( 566.60 - 550) / 550 × 100]

Solve:

566.60 - 550 = 16.6

16.6 / 550 = 0.0301818182

0.0301818182 × 100 = 3.0181818182

You may round that to 3.1%

So, Mr. Dawkins' salary increased by about 3.1%

It is the top one. the answer is -7. that is smallest
