Solution

For this case let :

x= number of adults

y= number of children

We can create the following equations:

x +y =8

5.5 x + 3.0 y=36.50

Then we can solve for x and we got:

x = 8-y

And replacing in the second equation we got:

5.5*(8-y)+ 3y = 36.50

44 -5.5y +3y = 36.50

44-36.50 =2.5y

7.5 =2.5y

y= 3

And for x we got:

x = 8- 3=5

Then the solution would be:

5 adult tickets
