Stephen went to the bank to cash a check. By mistake, the teller gave him dollars instead of cents and cents instead of dollars, which he didn't notice. On the way out, Stephen spent a nickel at a gum machine. When Stephen returned home, he found he had exactly twice the amount of the check.

Determine the exact amount of the check Stephen cashed at the bank.

Dollars = 31
Cents = 63

31.63 = (63.31 - 5) / 2
