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
Answer:
Step-by-step explanation:
x = $ 5 bags and y = $ 3 bags
x + y = 7.....this one is dealing with the number of bags
5x + 3y = 27....this one is dealing with the cost
x + y = 7.....x = 7 - y
now we sub 7 - y in for x, back into the other equation
5(7 - y) + 3y = 27
35 - 5y + 3y = 27
-5y + 3y = 27 - 35
-2y = - 8
y = -8 / -2
y = 4 <=== there are 4 three dollar bags
x + y = 7
x + 4 = 7
x = 7 - 4
x = 3 <==== there are 3 five dollar bags
