If 450 kilowatts of electric used cost 25.32, then how much would 240 kilowatts of electric cost?
first find how much one kilowatt costs.
so divide 450 kilowatts/$25.32 and you get your answer.
then take that answer and multiply to get the cost of 240 kilowatts.
I think we need to rethink this problem. If I divide 450/25.32 then multiply by 240 kw I get over $4,000. Shouldn't the cost of 240 kw be LESS THAN the cost of 450 kw; i.e., should't the cost of 240 kw be less than $25.32?
How abour 25.32/450 kw = cost of 1 kw.
And that times 240 kw or
(25.32/450)*240 = ?? cost of 240 kw.
You're correct, we need to adjust the calculations to find the correct cost of 240 kilowatts. Let's follow your revised approach.
To find the cost of 1 kilowatt, we divide the total cost of 25.32 by the total usage of 450 kilowatts:
1 kilowatt cost = 25.32 / 450
Now we can use this cost per kilowatt to determine the cost of 240 kilowatts. We multiply the cost per kilowatt by the number of kilowatts, which in this case is 240:
Cost of 240 kilowatts = (25.32 / 450) * 240
By evaluating this expression, we can find the correct cost of 240 kilowatts of electricity.
