1 answer:
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
