Answer:
95
Step-by-step explanation:
Let x represent the cost of adult tickets for $16
Let y represent the cost of children tickets for $6
x + y = 137...........equation 1
16x +6y = 1772............equation 2
Multiply equation 1 by 16 and equation 2 by 1
16x + 16y= 2192
-
16x + 6y = 1772
10y = 420
y= 420/10
y= 42
Substitute 42 for y in equation 1
x + y = 137
x + 42= 137
x = 137-42
x= 95
Hence 95 adult tickets were sold for $16 and 42 children tickets were sold for $6
