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%.

= [(209+69) - 239)] / (209+69)
= 39 / 278
= 39 / 278
= 14%

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

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