Question

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?

Answer 1

`color(green)("Increase % " = 16%, " rounded to whole number"`

Explanation:

`"Initial Salary " S_i = $ 120.00`

`"Revised Salary " S_r = $ 140.00`

`"Increase in Salary " I = S_r - S_i = 140 - 120 = $20`

`"Percentage Increase " I_p = (I / S_i) * 100 = (cancel20/cancel(120)^color(red)(6)) * 100`

`=> 100/6 % = 16.25% = 16%, " rounded to whole number"`
