Help! stuck on this word problem

There appears to be some info missing from the problem.
How many total tickets were sold in all?.
But, let x=# adult tickets sold and let y=# children's tickets sold.
Then, the total revenue is \(\displaystyle 14x+7y=1600\)
Now, assuming you mistakenly left out the 'number of tickets sold' portion of the problem.
Use it to set up the other equation. You then have two equations with two unknowns you can solve for x and y, the number of respective tickets.

I agree with galactus's approach - except:
revenue = 14 * x + 7 * y ← this is the answer to the question posed.
14 * x + 7 * y ≥ 1600
If we have only "=" in the above expression - we will have fractional "x" and "y"
