When a student sold an Xbox on eBay for $145, she was charged a two-part final value fee: 5.25% of the first $25 of the selling
Contact [7]
Selling Price = $145

Charge on first $25 is 5.25%
5.25% of $25 = \frac{5.25}{100}*25= \frac{5.25}{4} = 1.3125

Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 = \frac{3.25}{100}*120=3.9

Total\ charge=1.3125+3.9=5.2125 =\boxed{5.21}
