Answer:
Number of children = x = 330
Number of adults = y = 358
Step-by-step explanation:
Let
Number of children = x
Number of adults = y
x + y = 688 (1)
1.75x + 2.00y = 1293.50 (2)
From (1)
x = 688 - y
Substitute x = 688 - y into (2)
1.75x + 2.00y = 1293.50
1.75(688 - y) + 2.00y = 1293.50
1,204 - 1.75y + 2.00y = 1293.50
- 1.75y + 2.00y = 1293.50 - 1,204
0.25y = 89.50
y = 358
Substitute y = 358 into (1)
x + y = 688
x + 358 = 688
x = 688 - 358
x = 330
Number of children = x = 330
Number of adults = y = 358
