Answer:
[tex]70\ children\ tickets[/tex]
[tex]80\ adult\ tickets[/tex]
Step-by-step explanation:
Let
x------> the number of adult tickets
y------> the number of children tickets
we know that
[tex]x+y=150[/tex] -----> isolate the variable x
[tex]x=150-y[/tex] -----> equation A
[tex]10x+8.5y=1,395[/tex] -----> equation B
substitute equation A in equation B and solve for y
[tex]10(150-y)+8.5y=1,395[/tex]
[tex]1,500-10y+8.5y=1,395[/tex]
[tex]-1.5y=1,395-1,500[/tex]
[tex]1.5y=105[/tex]
[tex]y=70\ children\ tickets[/tex]
Find the value of x
[tex]x=150-70=80\ adult\ tickets[/tex]
