Hi
3week special:
Shop A: paying .92(.80) of original price 0r  .736 of original price
Shop B: paying .95((.895)y of original price
 .95(.895) y  < .92(.80) 

            y <  .92(.80)/ .95(.895) = .8656
      y = 14% off the third week

  .95(.895)(.86) = .7312 of selling price checks.  
Wish You the Best in your Studies.
