An electric supplier who previously supplied 1,850 feet of 1 1/2 inch conduit to the main LA county central warehouse, delivered the remaining of its stock to 25 remote outlying county warehouses. Of this remainder, each remote outlying warehouse received 650 feet of 1 1/2 inch conduit. What was the total amount of the conduit supplied?

The total amount of conduit supplied to the main LA county central warehouse is 1,850 feet.

The remaining of the supplier's stock is 1,850 feet - 650 feet = <<1850-650=1200>>1,200 feet.

Therefore, the total amount of conduit supplied is 1,850 feet + 1,200 feet = <<1850+1200=3050>>3,050 feet. Answer: \boxed{3,050}.

To find the total amount of conduit supplied, we first need to calculate the amount supplied to the main LA county central warehouse and then add the amount supplied to the remote outlying county warehouses.

1) To find the amount supplied to the main LA county central warehouse:
- The supplier supplied 1,850 feet of 1 1/2 inch conduit.

2) To find the amount supplied to the remote outlying county warehouses:
- Each remote outlying warehouse received 650 feet of 1 1/2 inch conduit.
- There were 25 remote outlying county warehouses.

Let's calculate the total amount of conduit supplied step-by-step:

1) Conduit supplied to the main LA county central warehouse: 1,850 feet
2) Conduit supplied to each remote outlying county warehouse: 650 feet
3) Number of remote outlying county warehouses: 25
4) Total amount of conduit supplied to all remote outlying county warehouses: 650 feet x 25 = 16,250 feet

Now, let's calculate the total amount of conduit supplied:
Total amount of conduit supplied = Conduit supplied to the main LA county central warehouse + Total amount of conduit supplied to all remote outlying county warehouses

Total amount of conduit supplied = 1,850 feet + 16,250 feet

Therefore, the total amount of conduit supplied is 18,100 feet.

To find the total amount of conduit supplied, we need to calculate the amount supplied to the main LA county central warehouse and the amount supplied to the remote outlying county warehouses, and then add them together.

First, let's calculate the amount supplied to the main LA county central warehouse. It is given that the electric supplier supplied 1,850 feet of 1 1/2 inch conduit to the main warehouse.

Next, let's calculate the amount supplied to the remote outlying county warehouses. It is given that each remote warehouse received 650 feet of 1 1/2 inch conduit. Since there are 25 remote warehouses, we can multiply 650 by 25 to find the total amount of conduit supplied to the remote warehouses:

650 feet/warehouse * 25 warehouses = 16,250 feet

Now, we can find the total amount supplied by adding the amount supplied to the main warehouse and the amount supplied to the remote warehouses:

1,850 feet + 16,250 feet = 18,100 feet

Therefore, the total amount of 1 1/2 inch conduit supplied is 18,100 feet.
