$16 per adult $9 per child
Because the second tour only had two more children, we can find the child price by: \[95-77=18\]\[18\div2=9\]So the child price is $9
Now that we know the child price we can find the adult price:\[9\times5=45\]\[77-45=32\]\[32\div2=16\]So the adult price is $16
That's all you needed to figure it out.
