When a student sold an xbox on ebay for $153, she was charged a two part final value fee: 5.25% of the first $25.00 of the selling price plus 3.25% of the remainder of the sell price over $25.00. Find the fee to sell the xbox on ebay.

well, just break the price into two parts: $25 and $128
so, the fee is
25(.0525) + 128(.0325)
