Please help. Really important At what percent above the cost price must an article be marked so as to gain 33% after allowing a customer a discount of 5%.

Step-by-step explanation:

x=costprice+profit+discount

Where profit is 33% of cost price and discount is 5% of marked price.

x=100+33+5x/100

x=133+x/20

x−x/20=133

19x/20=133

x=140

Cross check:

5% of 140 is 7 (discount). Price after discount is 133. And profit over cost price is 33, (133- 100) which is 33% of the cost price.
