3 weeks
To find how many weeks it will take, plug 52 into the equation as the Y variable and solve for x.
52 = 9 x + 25
Subtract 25 from both sides.
52 -25 = 9 x + 25 -25
27 = 9 x
Divide each side by 9.
27 /9 = 9 x /9
3 = x
And there you have it!
It'll take 3 weeks to fully fill the order.
Hope this helps!
