To solve this, I would just find what two adult tickets and one child ticket wold be worth.
To find that, just do:
5.20 + 9.90 * 2, which makes 25.
So now you just find how many 25s are in 900, or 36.
So 36 children's tickets were sold that day.
Hope I helped :)
Answer: Lesser = 19, Greater = 21
See picture reply.
Step-by-step explanation:
x-intercept => point (2, 0)
y-intercept => point (0, -4)
First you will divide 525 by 100. Then you multiply your answer by 4. That will equal 21
