Let x be the number of children and t, the number of adults.
x + y =153
5.2x + 8.4y = 1013.2
Solving those equation will give:
x = 85 tickets sold to the kids ( and 68 tickets for adults)

Answer:
<h2>$60.</h2>
Step-by-step explanation:
The cost for 0 cubic yards of gravel refers to the y-intercept of the function.
First, we find the constant ratio of change

The constant ratio of change is 32, that means the cost per cubic yard of gravel is $32.
Now, we just subtract this ratio twice to find the relations until we have x = 0.

So, for 1 cubic yard, the cost is $92.

For 0 cubic yards, the cost is $60, that's the y-intercept or the initial condition.
Therefore, the answer is $60.
its A
