Answer:
138 pairs
Step-by-step explanation:
The number of blue pleated slacks is 5 times the number of gray pleated slacks, so:
(eq1)
The number of gray non-pleated is twice the number of blue non-pleated slacks, so:
(eq2)
The total number of blue slacks is 333, and the total number of gray slacks is 225, so we have that:
(eq3)
(eq4)
If we add (eq1) and (eq2), we have:
(eq5)
Using (eq3) and (eq4) in (eq5), we have:


From (eq1), we have:

From (eq3), we have:

Keep in mind 1+1=10 and that 1+1+1=11:
Setup:
1 0 1 1
+ 1 1 1
------------------------------
(1) (1) (1)
1 0 1 1
+ 1 1 1
------------------------------
1 0 0 1 0
I had to do some carry over with my 1+1=10 and 1+1+1=11.
That would be the area of a circle of radius 12 miles
= pi r^2 = 452.4 square miles to nearest tenth.
