In my opinion, to use at least five dollar bills so as to make $62 you need to use the following bills. The fist one is 50 bill, two five bills and two single dollar bills. The total will give you $62 and you will have use at least five dollar bills.
If I was visiting your country I'd use 3 twenties and 2 ones. If I was at home in Canada I'd be SoL though, because fives are our smallest bills, making it impossible to make $62 with only paper money.
