Please show us your work, indicating exactly where you are stuck - so that we may know where to begin to help you.

So you're telling us that you cannot come up with equations for this:
"Total of 250 sets; 1 style @ $20, other style @ $45; total spending = $6,800.
Let x = $20 sets, y = $45 sets."

x + y = 250 [1]
20x + 45y = 6800 [2]

Can you solve those for x and y?
If not, then there's not much we can do; you need help from a teacher.
