1m = 1000mm, so divide 73c by 1000.
Then multiply by the amount used, 1250.
Then you will have your answer.
You have used 1250mm of 5mm M.S rod. The price per meter is 73c. How much does the money add up to?
If you don't like Gator's correct and good way to find your answer. Just use 42. It's works on all math problems :))))
