Mode 1 ā X% of Y: Y Ć X Ć· 100

Mode 2 ā X is what % of Y: X Ć· Y Ć 100
Example: 30 is what % of 200? = 30 Ć· 200 Ć 100 = 15%
Mode 3 ā Percent Change: (Y - X) Ć· X Ć 100
Example: 100 to 120 = (120 - 100) Ć· 100 Ć 100 = +20%
Mode 4 ā Increase/Decrease: X Ć (1 Ā± YĆ·100)
Example: $50,000 after 10% discount = 50,000 Ć 0.9 = 45,000
