Input Specification: Firstly, you will be given an integer (n, the number of transactions), then, a floating point number (euro2Leke, Euro to Leke conversion rate) where euro2Leke is smaller than 1e4. Then, your program will read n number of pairs:

• the type of transaction (1 is Leke and 2 is Euro) and
• a floating point number smaller than 1e5

Output Specification: Show one floating point number: total amount spent in leke.

Explanation: There are two transaction in leke (1200+1500 = 2700) and two transactions in Euro (20+30=50) Euro which makes (50*141) 7050 leke and the total is 9750 (2700 + 7050)
