If the store marks the shoes up 140%, then the selling price is (100+140)% cost, or 2.4 times the cost.
The pair of shoes then goes on sale for 15% off; or 85% of the original price. Thus: .85 x 2.4=2.04
Then, the clearance rack brings the price to:
.75 x 2.04=1.53
Then, the 10% off coupon; making it 90% of the clearance price:
1.53 x .9=1.377
Leaving the shoe store with 1.377-1, or a 37.7% profit above the original cost. ☺☺☺☺
