Question

mathstudent55 · Answer

(number of tickes sold) timex (price of each ticket) = cost of those tickets
Adult: x tickets, $8 per ticket; cost is 8x
Child: y tickets, $6 per ticket; cost is 6y
8x + 6y <= 172

....and then put that into the general form of a line and graph that line.

mathstudent55 · Answer

8x + 6y <= 172
6y <= -8x + 172
y <= -(4/3)x + 172/6
y <= -(4/3)x + 28.666...

mathstudent55 · Answer

Look at what b is in y = mx + b form. It's 28.666...
In choices a and c, b looks like 21, so that rules a and c out.

mathstudent55 · Answer

Choices b and d look the same to me.

mathstudent55 · Answer

They're the same. Maybe it's a mistake. They both look correct, though.
If you solve 8x + 6y = 172 for y = 0, you get x = 21.5, which looks like the x-intercept of both choices b and d. The y-intercepts also look like 28.666... in both, so I don't see any difference between the two graphs.

Perhaps if we could look closer, the scale on the graph might be weird or something?
