4 pts A manufacturer sells each unit for $8 to a wholesaler who marks up by 25% on their purchase price. Afterwards, the wholesaler sells the widget to retailers, who typically mark up by 33.33% on the wholesaler selling price. Here, the correct markup chain for retail selling price is: O $a"(1+25%)/(1-33.33%) $8*(1+25%)(1+33.33%) O 1$8/(1+25%) *(1-33.33%) O $8/(1-25%)/(1-33.33%) $8-1+25%)/(1-33.33%)
