Answer:
8 weeks
Explanation:
Ok, so the equation given is y=8x+40
If the school needs 104 cabinets in total, we have to find x, the number of weeks to complete this order.
We can input 104 as y as that's the total:
104=8x+40
We have to isolate x, so first, subtract 40 from both sides
64=8x
Next, divide both sides by 8
8=x
So, it will take 8 weeks to fulfill this order.
