Answer:
-4
Step-by-step explanation:
umm you might want to learn this. I cheated in middleschool/ highschool and was an honor student. I am barely surving college though, you'll need math for your general education requirement.
6.40x+9.90(154-x)=1230.90
Solve for x
X=84 for child
154-84=70 for adults
You can write it as 45/75 and simplify it by 5 to get 8/15
