Answer:

CHILDREN= 389

ADULT=310

Step-by-step explanation:

1) A + C = 710                          2) A*2.50 +  C*1.2 = 1288.75

OR, A= 710-C                            (710-C)*2.50 + C*1.2=1288.75

                                                    1775-2.50*C+1.25*C=1288.75

                                                    1775 -1.25*C = 1288.75

                                                    -1.25*C=1288.75-1775

                                                     1.25*C=486.25

                                                     C = 486.25/1.25

                                                     C = 389

                                         Again or, A + C = 710

                                                          A = 710 - C

                                                          A = 710 - 389

                                                           A = 321
