Question 73520: I solved this, but am not sure if I'm correct (the zero is making me think there's a trick):
1/6-1/3t>0
Here's what I came up with:
0/6-1/6+2/6 making t=1/6 which would be greater than 0. The interval notation would be: (0,1/6) and so on the graph, I would have two parentheses (one at zero, one at approximately 1/6). Did I do this correctly? Thank you for your assistance.

Question 76536: A small company produces both bouquets and wreaths of dried flowers. The bouquets take 1 hour of labor to produce, and the wreaths take 2 hours. The labor available is limited to 80 hours per week, and the total production capacity is 60 items per week. Write a system of inequalities representing this situation, where x is the number of bouquets and y is the number of wreaths. Then graph the system of inequalities.
Here is what i have so far:
x=40 items * 1 hour = 40 hours
y=20 items * 2 hours =40 hours
So I have the 60 items and the 80 hours, but how do I write a system of inequalities representing this and then how do I graph it. See I'm trying.
