a tickets at $45 per ticket cost 45a
c tickets at $32 per ticket cost 32c
The total cost is
45a + 32c
a is the best way to find it if there is points involved so keep that in mind
If the line is parallel, it has the same slope. So now just find the y intercept and put it into slope-intercept form
To find the mean, you have to add all the numbers then divide it by how many numbers there are.
In this case, you'll need to add all those numbers and divide it by 4.

The mean is 1995.
