Question

how to figure single equivalent discount rate

Answer 1

10% discount = 10*95/100 = 9.5. Remaining amount = 85.5. 15% discount = 15*85.5/100 = 12.82 ( rounded off to 2 decimal) Total discount = 5+9.5+12.82 = 27.32. Since the initial price assumed is $100, single equivalent rate of discount is 27.32%
