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......

A. 11% B. 25% C. 44% D. 56% E. 125% I was a bit shocked at current stats of 45% incorrect. Sometimes a simple sketch, for me, is better than an equation. Andrew's savings from beginning to end of each year: Year 1: 0$ ------> $240 Year 2:$240 ----> $540* Year 1 amount saved is$240
Year 2 amt saved is (540 - 240) = $300 Percent increase = $$\frac{change}{original}$$: $$\frac{(300-240)}{240}$$ = $$\frac{60}{240}$$ = $$\frac{1}{4}$$ = .25 x 100 = 25% Answer B *(Careful, maybe: I think it would be easy to misread "by the end of 2 years he had saved a total of$540" incorrectly as "at the end of the second year he had saved [another] $540." The latter yields answer E.) _________________ SC Butler has resumed! Get two SC questions to practice, whose links you can find by date, here.

Difference of 2 years savings and 1 year savings = 540 - 240 = 300 ---> 2nd year savings
% increase in two years = (300 - 240)/240 * 100 = 25%
Option B

IMO B

amount saved in first year 240

amount saved at the end of second year 540

extra amount saved only in second year = 300

extra amount saved = 60

in percent = 60/250*100 = 25%
