If the markup formula is 40percent of cost and the selling price is 49.99what is the cost / a 31.76 b 33.33 c 34.33 d 35.71

An item, x, is marked up 40% and now costs $49.99

40% is 0.40

1 times any number will be the same number so we'll use that to add on the original price to the amount of increase

(1+0.40) x=49.99

x=49.99/1.4

x=35.71 so D is the answer
