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:1/12
Step-by-step explanation: if the loop 11/12 of a mile and she rode for 1/2 of a mile then 1/3 , subtract what she rode from 11/12 then you get 1/12
This would be a proportion:
7 4*7
---- , ------- NOTICE THAT 4 IS THE MULTIPLIER IN BOTH CASES
16 4*8
BUT
7 4*7
---- , ------- WOULD NOT BE A PROPORTION. 4 AND 10 ARE DIFFERENT
16 10*8 MULTIPLIERS.
