Algorithm Training P1101time limit: 1.0s memory limit: 256.0MB 　　
There is a bill of lading whose data items are: Product name (MC), Unit Price (DJ), Quantity (SL). Defines a struct prut whose members are the three data above. Define a struct-body array of type Prut in the main function, enter the value of each element, and calculate and output the total amount of the bill of lading.
Input format: The first line is the number of data items N (n<100), followed by each row is a data item. The product name is a string that is not more than 100 in length, the unit price is double, and the quantity is integer type.
Output format: The total amount of the double type.
Input:
4
Book 12.5 3
Pen 2.5 10
Computer 3200 1
Flower 47 5

Output:
3497.500000
