Kid tickets = 3d
D = adult tickets
448 = (3 * d) + d
448 = 4d
448/4 = 112
112 = d
3 * d = 336
There are 336 kid tickets and 112 adult tickets sold.
Answer:
6x^2+10x-6=0
Step-by-step explanation:

Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.
x+y=170 (We know that soda + dogs is 170)
x-50=y (We know that dogs is equal to 50 less than sodas)
We can use substitution to solve this system of equations.
x+y=170
Sub in the value of y from the second equation
x+(x-50)=170
2x-50=170
2x=220
x=110
We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.
x+y=170
110+y=170
y=60
So, there were 60 hotdogs sold and 110 sodas sold.
