Final answer:
The jersey price during the playoffs, after the additional 25% markup, was $113.44.
Step-by-step explanation:
The sporting goods store owner first marks up the jerseys at his standard retail markup of 65%. When the local football team reaches the playoffs, he adds an additional markup of 25%. The question seeks to find out the price of the jerseys during the playoffs.
First, let's calculate the store's standard retail price:
- The wholesale price of one jersey: $55
- Retail markup: 65% of $55 = $35.75
- Standard retail price: $55 + $35.75 = $90.75
Next, the price during the playoffs with an additional 25% markup:
- Additional playoff markup: 25% of $90.75 = $22.6875
- Price during playoffs: $90.75 + $22.6875 = $113.4375
The jersey price during the playoffs was $113.44, rounded to the nearest cent.
