(A) 14%

(C) 29%
(D) 33%
(E) 86%

= [(209+69) - 239)] / (209+69)
= 39 / 278
= 39 / 278

(A) 14% (B) 16% (C) 29% (D) 33% (E) 86% For estimates, just round the numbers to 210, 70, and 240. Thus, Savings = (210 + 70) - (240) = 40 Amount Saved/Total Cost = 40/280 = 1/7, then some quick division gives you an estimate of 14%.

(A) 14%

Total cost whenbaought seperately = 209+69=278
Extra cost paid = 278-239=39

Amount saved = 39*100/278=14% answer A
