Calculating the Average Lifespan of a Compact Fluorescent Lamp (CFL)

The average lifespan of an incandescent light bulb is 1000 hours. Let's calculate the average lifespan of a compact fluorescent lamp (CFL) and the number of incandescent light bulbs needed over the lifespan of the CFL.

Step 1: Calculate the Average Lifespan of a CFL The average lifespan of a compact fluorescent lamp (CFL) is 15 times longer than that of an incandescent light bulb.

Using the given information, we can calculate the average lifespan of a CFL: Average lifespan of CFL = 1000 hours * 15 = 15000 hours

Step 2: Determine the Number of Incandescent Light Bulbs Needed To determine the number of incandescent light bulbs needed over the lifespan of the CFL, we can use the following calculation: Number of incandescent light bulbs = Lifespan of CFL / Lifespan of incandescent light bulb

Number of incandescent light bulbs = 15000 hours / 1000 hours = 15 incandescent light bulbs

Therefore, the average lifespan of a compact fluorescent lamp (CFL) is 15000 hours, and over the lifespan of the CFL, 15 incandescent light bulbs would be needed.
