Answer:

If a fluorescent bulb uses 2,000 kilowatt-hours, then the amount of energy used as light is 1500.

Explanation:

The question provides us with all the information we need very simply. It wants to find 75% of 2000. In order to find 75% of 2000, first we must convert 75% into a decimal, which we can do by moving the decimal point two spaces to the right. In this case, 75% as a decimal would be 0.75 Now, all that is left is to multiply 0.75 by 2000. 0.75 x 2000 is 1500.

If a fluorescent bulb uses 2,000 kilowatt-hours, then the amount of energy used as light is 1500.
