(I need this math problem solved really quickly; A cash register contains only five dollar and ten dollar bills. It contains three times as many five dollar bills as ten dollar bills and the total amount of money in the cash register is $1,175. How many ten dollar bills are in the cash register?/ It's straight forward, but I can't find the time to work it through, can someone solve it please? Thanks)
