Children’s tickets are $4, adult tickets are $14
Explanation:
4a+6c=80
If they made $4 more dollars on the second day than the first by selling one extra child ticket then we know a child’s ticket is $4 per ticket.
4a+6*4=80
4a+24=80
4a=56
14=a
So each adult ticket costs $14.
You can check by filling in $14 and $4 for each equation.
4*14+6*4=80
4*14+7*4=84
Answer:
the answers are:x1=-4 and x2=5
Answer:
The Answer is: x / y = 8 / 3
Step-by-step explanation:
3(x - 2) - 4(2y - 1) + 2=0
3x - 6 - 8y + 4 + 2 = 0
3x - 8y = 0
3x = 8y
3x/y = 8
x / y = 8 / 3
