275 students and 113 non-students attended the event.
Step-by-step explanation:
Let,
Student ticket = x
Non-student ticket = y
Price of one student ticket = $3.50
Price of one non-student ticket = $5.50
According to given statement;
x+y=388 Eqn 1
3.50x+5.50y=1584.00 Eqn 1
Multiplying Eqn 1 by 3.50
Subtracting Eqn 3 from Eqn 2
Putting y=113 in Eqn 1
275 students and 113 non-students attended the event.

Let the width of table B be w, and since area of table A = area of table B, then 6 2/3 x 3 1/2 = 4 1/4 x w [this is the required equation]
20/3 x 7/2 = 17/4 w
17/4 w = 70/3
w = 70/3 / 17/4 = 70/3 x 4/17 = 280/51 = 5 25/51
