Answer:
170 tickets.
Step-by-step explanation:
Write formulas for the question.


Then use substitution.




So number of $3 tickets sold is 230. But they ask for the tickets bought in advance (i.e. the tickets sold for $2). Use substitution again.

multiply both sides by the reciprical of 5/3 so:
3/5(5/3)w=-10(3/5)
w=-30/5= -6
Disjunction would be statements connected with <span>or.

Answer:
$8.40
Step-by-step explanation:
We can write a proportion to find the total amount last year using the information given. A proportion is two equivalent ratios set equal to each other.

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
125(y)=100(10.50)
125y=1050
y=8.40
First you add250+250 then you add 9+9 or you could do250×9 2 times then add them together . never mind just do 250×9 2times and that will eqaul 2,250 then add 2250+ 2250and you got the answer and the answer is 4500
