Answer:
- adult: 325
- children's: 225
Step-by-step explanation:
It usually works well to let a variable represent the higher-value item in the mix. Here, we can let 'a' represent the number of adult tickets sold. Then the total revenue is ...
1.50a +1.00(550 -a) = 712.50
0.50a = 162.50 . . . . . . . . . . . . . subtract 550 and collect terms
a = 325
c = 550 -325 = 225
325 adult and 225 children's tickets were sold.
There is no solution. Because the absolute value function finds the distance between the number and 0. And length is never negative.
So, |-x| = -10 has no solution.
If you're talking about just the decimal, then yes it is.
If you're talking about 22/7, then it still is.
But if you're talking about pi, then it isn't rational.
