Emily made $35,000 a year her first year out of nursing school. She now earns $90,000. What is the percent of increase or decrease?(could you please show work)
The increase is $90000 - $35000 = $55000
Expressed as a fraction of her initial salary this is 55000/35000 = 55/35 = 11/7
To express this as a percentage, multiply it by 100: 100*11/7 ≈ 157% (Don't forget to put the % sign after the number).
