Percent increase in the amount Andrew saved during the second year compared to the amount he saved during the first year.
Percentage Change = ( Change in value / Original value ) * 100
Percentage Change = [ (Saving in 2nd year - Saving in 1st year ) / Saving in 1st year ] * 100
Saving in 2nd year + Saving in 1st year = 540
Saving in 2nd year + 240 = 540
Saving in 2nd year = 540 - 240 = 300
Change in Value = 300 - 240 = 60
Original Value = 240
Percentage Increase = (60 / 240 ) * 100 = (1/4 ) * 100 = 25 % ..... Answer B......
