On a certain day, the company took 103 people on a whale watching trips. There were 64 children aged 12 and under, of which some children were under 3 years. If x represents the number of children under 3 years, which equation can be used to find the value x, where C represents the total amount of money collected from tickets that day?

A(64-x)34+(103-64)×45=C
B(103+x)34+(103-(64+x))×45=C
C(103-x)34+(103-64)×45=C
D(64+x)34+(103-(64+x))×45=C
