Answer:
8 adults
Step-by-step explanation:
The proper equation to find the number of adults is as follows...
(1 x 5) +(10x) = 85
Since there is only one child will will have 1 ticket for a child. hint ( 1 x 5)
Since we need to find the total number of adults at the movie group we will put (10x)
Since the total cost is 85 we will have it equal to $85
Now time to solve
5 + 10x = 85
first subtract 5 from both sides ( 5 - 5 ) and ( 85 - 5 )
10x=80
Now divide both sides by 10 ( 10x/10 ) and 80/10
x=8
So there are 8 adults.
