A birthday party at Party Place A costs $8 per child plus a cleaning fee of $72. a birthday party at Party Place B costs $12 per child. Which equation can be used to find c, the number of children attending the party, so that the total charge at Party Place A is equal to the total charge at Party Place B? F 8c-72 = 12c
G 12C+72=8c
H 12C+8c -72
J 8c+72 = 12c
