Answer:
x = 76 children's tickets sold
Step-by-step explanation:
Let x = the number of children's tickets sold
Let y = the number of adult tickets sold
x + y = 131
5.5x + 9.8y = 957 Solve the first equation for y
y = 131 - x Multiply the second equation by 10
55x +98y = 9570 Substitute the above equation into this one.
55x + 98(131-x) = 9570 Use the distributive property
55x + 12838 - 98x = 9570 Solve the equation
-43x = -3268
x= 76 children's tickets sold
Answer:
x=12the opposite side of parallelogram are equal
Explanation:
_______________
Price starts at: $7.37.
__________________
The first month, it increases by $0.50, so we add $0.50 to that starting value:
__________________
$ 7.37
+ 0.50
___________
$ 7.80
_____________
The second month, it decreases by $0.38, so we subtract $0.38 from our last obtained value:
___________________
$ 7.80
- 0.38
___________
$ 7.42
______________
During the third month, it increases by $0.32, so we add $0.32 to our last obtained value:
______________
$ 7.42
+ 0.32
___________
$ 7.74
______________
During the fourth month, it decreases by $0.12, so we subtract $0.12 from our last obtained value:
________________________
$ 7.74
- 0.12
___________
$ 7.62; which is our answer.
_____________
How do we know our answer is reasonable?
______________
We start with: $7.37, then plus $0.50, then minus 0.38, then plus 0.32, then minus 0.12.
_______________
The "minus 0.38"and "plus 0.32" do not "cancel out" , but come close to. The "plus 0.50" and "minus 0.12"; in consideration with the above sentence; suggest that the value should be over the starting price of $7.37, but not much more than $8.00; or even less than $8.00.
Our answer is: $7.62; which seems "reasonable".
