Answer: Cost of adult ticket is $10.75.
Step-by-step explanation:
Since we have given that
Total cost of the six tickets = $40.50
Number of adults = 2
Number of children = 4
Let the cost of child's ticket be x
Let the cost of adult's ticket be y
So, According to question,
[tex]y=x+6---------(1)\\\\and\\\\2y+4x=\$40.50---------(2)[/tex]
Put the value of Eq(1) in Eq(2), we get
[tex]2y+4x=\$40.50\\\\2(6+x)+4x=40.50\\\\12+2x+4x=40.50\\\\6x=40.50-12\\\\6x=28.5\\\\x=\frac{28.5}{6}\\\\x=\$4.75[/tex]
So, The cost of child's ticket is $4.75
Hence, the cost of adult's ticket will be
[tex]y=x+6=4.75+6=\$10.75[/tex]
Therefore, Cost of adult ticket is $10.75.
