Answer:

  C. The same number of guests attended Rick and Tom's party.

Step-by-step explanation:

Let R and T represent the number of guests at Rick's and Tom's parties, respectively. The charges Rick and Tom paid are equal, so we have ...

  65 +25R = 40+25+25T

  25R = 25T . . . . . . . . . . . . subtract 65

  R = T . . . . . . . . . . . . . . . . . divide by 25

The number of guests at each party is the same.
