# With the new pay scale, Nick's salary went from $120.00 a day to$140.00 a day. What is the percent of increase rounded to the nearest whole number?

color(green)("Increase % " = 16%, " rounded to whole number"
"Initial Salary " S_i = $120.00 "Revised Salary " S_r =$ 140.00
"Increase in Salary " I = S_r - S_i = 140 - 120 = $20 $\text{Percentage Increase } {I}_{p} = \left(\frac{I}{S} _ i\right) \cdot 100 = \left(\frac{\cancel{20}}{\cancel{120}} ^ \textcolor{red}{6}\right) \cdot 100\$
 => 100/6 % = 16.25% = 16%, " rounded to whole number"
