It will cost $6000 to buy 3 kilometers of wire.
Step-by-step explanation:
Given,
Cost per meter of wire = $2
We have to find the cost of 3 kilometer of wire.
As the cost of wire is given in meters, we will convert meters in kilometers.
1 kilometer = 1000 meters
3 kilometers = 3*1000 meters
3 kilometers = 3000 meters
Cost of 3000 meters of wire = 2*3000 = $6000
It will cost $6000 to buy 3 kilometers of wire.
