Question 167790
Note: 22% = {{{22/100=0.22}}}



In this case, the cost to the retailer is {{{C=40}}} and the percentage rate is {{{r=0.22}}}. 



{{{S=C+rC}}} Start with the markup cost formula. Note: the other formula is used for discounts



{{{S=40+0.22(40)}}} Plug in {{{C=40}}} and {{{r=0.22}}}. 



{{{S=40+8.80}}} Multiply



{{{S=48.80}}} Add



So if the cost to the retailer is $40.00 and they use a markup of 22%, then the selling price is $48.80
