Answer: There are 50 adult tickets and 62 student tickets.
Step-by-step explanation:
Since we have given that
Cost of adult ticket = $ 6
Cost of student ticket = $ 4
Total cost = $ 548
Number of adult ticket be 'x'.
Number of student ticket be 'x+12'
According to question, we get that,
6x+4(x+12)= 548
6x+4x+48 = 548
10x = 548-48
10 x = 500
x = 500 ÷ 10
x = 50
x + 12 = 50 + 12 = 62
Hence, there are 50 adult tickets and 62 student tickets.
